Version 7.17.1 keeps crashing and re starts my smartphone every time I use it. Huawei Nova 3. Also Impossible to take screenshots anymore which goes against helping students to takes notes and learn. Do NOT update. Thinking of asking for a refund of ALL my classes. Edit: even on a new phone I still have to uninstall and re install the app many times to just use it as I keep getting logged out and it's impossible to login again.
