I’m not sure if this applies in your case, but I was having trouble signing up and logging in. The mobile web version just hung as if it was thinking and never progressed to success or failure. I was able to complete both functions successfully using a password manager on the desktop website (show as desktop site on mobile browser), but was unable to login in Jerboa on Android. I was using a 63 character password.
I changed my password on the desktop site to a temporary 12 character one and everything worked fine. I went looking for what the maximum password length is and got a hint that it may be 60 characters in the Jerboa app. I changed my password to 61 characters and had the same problem, but then 60 characters worked fine everywhere, confirming that to be the problem.
If your password is over 60 characters, try a shorter one and see if that solves your problems too? Let us know how it goes.
