[INCONSISTENT] No connection / can't log in

[Der-Flip]

For a couple of days now, I cannot get a connection. I cannot log in to my Deezer account through the app. both methods (log-in an-app + website + ARL) don't succeed. with the former showing me a gray screen and the latter two an infinite loading circle...
I checked my Deezer Account and it's still accessible.
I tried deleting all of the app's data through the System settings to no avail.

The initial symptoms were that I couldn't search or play any songs anymore. When I checked the settings I noticed the app was in offline mode and I was unable to deactivate it.

EDIT: After closing the app on the infinite loading (ARL login) and starting it again, I can now play and download again, but the Start tab is infinitely loading and showing no content.
