Your App is Crashing - Please Update Soon

Piazza is a valuable tool for many classes but the app is crashing very frequently with iOS 13. Specifically, the app crashes when composing a response to a question and then does not save the draft of the response so one has to start over. This is very inconvenient.

Something is now broken about login on iOS

I tried clicking App Support to file a big report, but that only takes me to the piazza website, which is not the purpose of that button, so I’m forced to file a bug report as a bad review. :(

About 1/3 of the time when I answer a student question or add a follow up comment on iOS, when I click the check mark to submit the answer or follow up, the iOS app now kicks me back to login and forces me to enter my password again, completely erasing the answer text I entered in the process. This is a NEW problem and makes the app incredibly unreliable. Please fix it.

Piazza is great, but this app is not.

Piazza is a fantastic resource in all of my classes, but I have been disappointed by the mobile app. Instructor answers to follow up questions are not highlighted, the editor for creating a new question/ responding to a question is very clunky and lacks nearly all of the formatting options provided on desktop, and the overarching interface feels more like a half-baked mobile website than a dedicated app. Really hoping this is updated and improved at some point.
