News app is https://play.google.com/store/apps/details?id=de.luhmer.owncloudnewsreader

Do you have any account in your NC files app?

[smaugilein]

Two, in fact. The fc occurs on both accounts.

[tobiasKaminsky]

@David-Development do you have an idea?

Here we do check if account exists…

@smaugilein What is the Version of the Nextcloud News App? Maybe you can test if the beta version of the nextcloud news app works for you?

@tobiasKaminsky Ugh.. 😅 Looks like it is not picking up that account.. right? Maybe some permission issues..? Maybe it's just a problem with the stable version of the news app because it is using a quite old version of the sso library.. Maybe I should push the beta to stable soon 🙈

[tobiasKaminsky]

Would be worth a try :-)

[smaugilein]

@David-Development I got the latest version from the Google play store. V0.9.9.25.
Beta version test will follow in a minute!

Thanks for caring!

[smaugilein]

Ok, the beta is working like expected. Seems to be a news app (stable) related problem. Thank you so much for your help!

[tobiasKaminsky]

Glad that it is working.
