I am unable to Login on my android phone. Okay on my computer and iPad.
Please clarify how exactly can you not log in?
You open the app, see the login screen and what do you do then - tap on "Login" or "Enter with Google"? What happens then? Does the app crash, do you see error messages, do you use the same login credentials as on the web?
Also, what version of Android and our app are you using?
