I was prompted to upgrade my iPhone app on my iPhone 6 with iOs 11, and I did. I also upgraded the system. After this, Spotify and Soundcloud is working fine. TIDAL ask for re-authorization, I follow the link, performs this, returns to TIDAL, and I am asked again! Performing the authorization a second time, returning, and still the same message. I stop and restart the app, and I turn off and on my phone, with no effect on this, I'm stuck!
