Vaultwarden Support String
Hi guys, I am not sure if my current issue has to do with this (new device registration awaits SMTP #5856) but let me explain:
I was using the (always latest) Bitwarden App fine with my self-hosted Vaultwarden, which was some older version.
Today I tried to create an App that communicates via API to store secret notes. After some trial and error I got the connection to work but realized I used my personal API Key instead of the organization one.
After the first successful login of my new server-app - my Android App stopped working and only shows "unable to process your request".
I can login to the Bitwarden Web Clients and the normal Web GUI with this account and also I can login with other accounts on my android app and see their contents just fine. But my own user is not accessible via App. I rotated all secrets and KDF but nothing worked.
Of course I restarted the server (and later also updated it to 1.35.2) and deleted the Android App multiple times. I still can see the "android" in my "Apps" View on the Web Interface but can not delete it from there. I also disabled the 2FA for the account but also no success
I think it is seen as a new device and could be connected to #5856

Additional Context
Do I just need to rotate the main encryption code (master key tab) like explained here?
https://bitwarden.com/help/account-encryption-key/#rotate-your-encryption-key
I just did the other two rotation options (keys tab)
