Great App in total with only a few small complaints I collected: • No dark mode – It would make the app so much easier to use in morning hours and fit better into dark systems. • The course list can't be simply edited; only reset and redone – Especially, when there is only one course that was mischosen this is a big hassle • Limited colors for courses – This is my last and a rather small complaint, but with more than just a few courses it would definitely be helpful to get a few more color choic

Functionality ok. But it uses an IMMENSE amount of mobile data or wifi data. Seems to be downloading the photos attached to recent posts over and over, each time I open the app. Just now I opened the app and it downloaded 1GB (over wifi), due to a bit of scrolling through recent posts (to which the teacher had added maybe 100 - 150 photos). I can't chance that behavior via Settings. The downloads continue even as I send the app to background. :-(

This app is hacked. One of the hackers easily hacked into my son's account. When we sought support, they responded twenty days later with a foolish reply, saying, "My email is in someone else's account!!!" They completely ignore messages and, of course, the school administration shows no concern about the matter. I'm telling you, This app is hacked.
