aussie.zone has updated ik because I enabled MFA and it says so at the bottom of the page. The error I got was incorrect password (it was the correct password, I checked)
Which version of jerboa are you on? The play store seems to still be on 0.33 and crashes on login for me.
If you are on a newer version try disabling 2fa? That should tell you if it's the cause. I saw another post suggesting Jerboa doesn't have the flow yet to put in the 2fa code but I don't know which version if the app they were on.
