After Upgrade to Nextcloud v25 NC Client for Android cannot login to grant access

Hi,

after I updated the server to NC v25.0.2, I had to update my desktop client from v2.5git to v3.6.4, in order to (re-)grant access to the server.

Now I have the same behaviour with my nextcloud client on Android: On the page with the “Login” button and “Alternative Anmeldung mittles App-Token” , the latter does nothing, and the button forwards to an empty page with the NC background.

The same clients work with Nextcloud v24, the login button goes to my nextcloud server and the login prompt is shown and login via app token displays two test boxes for username and token.

I was able to authorize the client using the QR Code shown on the security page in nextcloud.
