Unable to log in

[Augustinit]

I can't seem to be able to log in into my account. I enter the right email address and password and press log in, the button changes to "logging in" and then switches back to "log in" after a couple of seconds with no error message or anything else. If I keep pressing it it does the same thing all over again.

This exact thing happens to me as well. I'm on a Moto E4, tried reinstalling the app multiple times, still didn't work.
