To-Do List Functionality Broken After Recent Update
Users report that the To-Do list no longer displays upcoming assignments correctly, shows outdated or incorrect due dates (e.g., only showing Sunday-Saturday instead of a rolling week), fails to auto-populate, and does not reflect completed tasks. Many users demand a rollback to the previous version.

reviews
- “The new update made the app harder to use — This new UI update has made the app more confusing. It’s trying to tell me I have 3 missing assignments from a class I took 4 years ago in a degree I have already completed.”
- “To do list — Please reverse the app back to the old to do list AND LEAVE IT ALONE. PLEASE!! I don’t want to have to manually check off assignments.”
- “The to-do list is continually in an unhelpful error state. 'Something went wrong' does absolutely nothing to help me solve the problem.”
App Freezes and Crashes on Grades and Scroll Actions
Frequent freezing and crashing occur specifically when scrolling through the Grades tab, Assignments, or during navigation. The issue persists across devices and iOS versions, rendering the app unusable for core functions.

reviews
- “Canvas freezes on the Grades Tab and Assignments tab — Canvas freezes scrolling through the “Grades” tab inside a course and on the “Assignments” tab.”
- “Freezes while checking grades — The app freezes when I checked my grades. Even when I wait a few seconds before scrolling down, it would still freeze.”
- “App crashes every time you try to edit your calendars — If you want to add a new class to your calendar, then you must select the calendar list. Scrolling down the list will cause the app to crash before you can add your required class”
Security Breach and Data Privacy Concerns
Multiple reviews cite a recent hack or data breach, expressing fear over personal data exposure, loss of trust in the platform, and frustration with vague communication (e.g., calling it 'routine maintenance').

Poor Performance and Slow Loading Times
Users report extreme slowness in loading content, especially after updates. Pages take minutes to load, links from emails fail to open, and the app feels sluggish despite modern hardware.
29
reviews
- “Fix your app — Filled with bugs that make it next to impossible to get assignments done. Needs 10 minutes to load anything (I’m on the latest IOS version on Iphone 14).”
- “Slow — UI is good, everything works well except for the fact that it’s extremely slow when loading things, wont load a lot of the times when forwarded to by a link from emails, notifications, etc.”
- “It takes so long to load now. i have no idea why it needed to be liquid glass.”
New UI/UX Design Is Unintuitive and Degrades Usability
The redesigned interface is criticized as cluttered, confusing, visually unappealing, and functionally worse than the previous version. Users miss clear navigation, distinct pages, and familiar layouts.
27
reviews
- “Horrible UI — This new UI might be the worst UI I have ever seen, PLEASE fire the designer of it and go back to the old design”
- “The new update made the app harder to use — This new UI update has made the app more confusing. It’s trying to tell me I have 3 missing assignments from a class I took 4 years ago...”
- “New UI design is very ugly — Never wrote a review to an app before but I'm sorry to say that the new UI change to integrate's Apple's 'liquid glass' is not very tasteful.”
Notifications and Assignment Visibility Issues
Critical features like assignment due date alerts and visibility are broken. Notifications are delayed, missing, or irrelevant; assignments don’t appear in the To-Do list until too late.
22
reviews
- “No notifications for assignments. — Exactly what the title says. I don’t get notifications for assignments or quizzes being assigned.”
- “Assignment grade notifications don’t work right — Whenever I receive a notification about an assignment getting graded and or having a submission comment and I click on it, the app DOES NOT LOAD my assignment.”
- “After the recent update, my to-do list isn’t populating upcoming tasks. Due to this I have missed a few assignments.”
Inconsistent or Non-Functional Features on iPad
Key features such as video playback, file access, module accordions, and calendar display are broken or inconsistent on iPad, despite working on other devices.
15
reviews
- “Cannot open accordions on iPad — The app is useless on an iPad. It is inconsistent in playing videos, cannot open accordions in modules, and does not instill confidence if one wants to take tests on the iPad.”
- “Can't Access Assignments on iPad — Many students use iPad to complete their assignments, including me. It's unacceptable that as of a month or so ago, I have been unable to access any files uploaded to Canvas, *exclusively* on my iPad.”
- “My to do list disappeared — I have reached out to get help and NOTHING. Suddenly my To Do List is gone and it is what keeps me organized - I hate i have anxiety about missing an assignment all the time now.”
Persistent Bugs and Glitches Across Multiple Functions
A wide range of recurring bugs: text disappearing in assignments, notes corrupting, videos losing progress, form submissions failing, and random crashes unrelated to specific screens.
25
reviews
- “Bug — There is a bug where when I exit an assignment and come back, all the text dissapears.”
- “Notes always get deleted — I swear to god 8/10 times the notes I’m taking on files in my class get like half deleted or corrupted it is absolutely miserable.”
- “Clears Responses — I open an assignment, I type out my paragraphs, I hit submit, what does it do? Not submit, that’s for sure.”

First load takes ~60–120s. Cached after.
