I agree with the other most recent review. There must have been a recent update, which has rendered the app useless on my android device. When clicking on the school's blackboard link, I get an error message stating null check operator on a null value. It works fine on a laptop/desktop version, but when trying to work on your phone, it's not an option now.

Very glitchy. Not sure if it's my phone, pixel fold, but whenever I try to scroll down or up, the screen spazzes out and it's scrolling all over the place. If I have the app open and click the "lock" button on my phone, it doesn't actually lock. Those are the 2 major bugs I found. When it does work and I can actually scroll, it's good

The app is okay at best. The web browser version is a ton better than this. At least in the browser it saves your progress. Occasionally everything goes blank on the app. Also, the knowledge checks/quizzes are sometimes impossible to use if you have a device that uses gesture controls at all. My advice is to use the web browser version from a pc, Mac, or Linux instead the mobile app.
