Research direction

Start by reproducing the Cardskipper login flow on Android 13 and reviewing the attached logcat.log, using the reported microG and /e/OS versions as context. Trace the login failure from the app interaction into the relevant authentication path; done means valid credentials log in successfully or the failure displays a meaningful error instead of a blank message.
