I have the same problem, kind of, but a login attempt in a desktop browser gives me the error code BID-2033 all the time (which is described as a communications error in that list you mentioned, that should be caused by a bad data connection), so dunno what that’s about, my connection on both wifi and 4G is good.
I tried removing cache and things, giving it all permissions and enabling Exploit protection compatibly mode first, uninstalled/re-installed the BankID app, and now it just crashes upon trying to open the app at all so I can enter my credentials, but no go, just crash upon crash.
Maybe try installing an earlier version? Haven’t tried that. Or wait for an update and use the banking code thingy meanwhile?
