Have had this setup running for at least 5 years, works flawlessly, and running it in a docker container meant all I had to when moving to a new homeserver was copy the config file

Jeg kan bekræfte at Nordea virker uden problemer, og med deres egen id app slipper du helt for mitid til alt med mobilbank, jeg har ikke erfaring med andre banker

Det virkelig fjollede ved hele det her problem er også at android i hvert fald, har indbyggede integritetstjek der kan benyttes i stedet for play integrity. Det er generelt i emne der konstant diskuteres i GrapheneOS miljøet.

Jeg kan bekræfte mobile pay virker uden problemer, men jeg opgav mitid og bestilte en gratis kodeviser.

How about you use eReolen which is the Danish library app available to all Danish citizens. It even incloudes audiobooks.

For the time being MitID is still broken due to the play store integrity check, most of the Danish community opted for the free hardware code generator, I tried to get MitID chip working I have given up getting to even finish the setup. The code generator works flawlessly. For banking I can vouch for Nordea, and with their own ID app you don't even need MitID for banking. Mobile pay complains if you don't have sandboxed play services.
