Android 3.12.0 doesn't save my user / login

Hallo forum

I have strange error with my Huawei P30 pro phone
I have installed the newest version of Nextcloud from google store

I have a Owncloud server running (docker) that works fine.

It seems that i can login once with my user , but every time i close the app on the phone and opens it again, i have to login , so it doesn’t save my user…

Any of you guys have seen this before?

And to mention i had it working on my old phone (Samsung Galaxy S8 w. newest Nextcloud)

Thanks in advice…
