Users cannot login to version 7.0.1 even though logs show Login Successful

Using Nextcloud AIO version Version
[Nextcloud Hub 10 (31.0.6)

And Nextcloud iOS 7.0.1 - users are now not able to achieve a successful login to the APP.

With a fresh install of the app, they enter the server address and come to the login screen

Enter username and password

Click on Grant Access then it goes back to login screen and this message in logs

"message": "Login successful: "REMOVED"",
"userAgent": "Mozilla/5.0 (iOS) Nextcloud-iOS/7.0.1",
"version": "31.0.6.2",

Waited and no change

After tried again and it said Access forbidden - State Token Missing

and this message in logs

"message": "Logout occurred",
"userAgent": "Mozilla/5.0 (iOS) Nextcloud-iOS/7.0.1",
"version": "31.0.6.2",

If selecting Log in with a device (for accounts that have that set up) - entering the user name and clicking Log in - nothing happens - no indications - nothing.

iOS version on phone is 18.5 (22F76)

Tried to reboot phone and same thing

Seeing this with multiple users

Start by reproducing the login and device-login flows with Nextcloud iOS 7.0.1 against Nextcloud Hub 10 (31.0.6), using the reported logs and iOS 18.5 environment. Trace where the successful login returns to the login screen and where the state token is lost. Done means affected users can complete both applicable login flows without the forbidden or no-response behavior.
