Android TV 6.0: It asks to sign each time

[Jecht_Sin]

I have a Sony Bravia television with Android TV 6.0. Spotify used to work fine, now it has been few days that it keeps asking to sign in each time I open it. If I sign in with username/password on the television, or via the phone or computer it connects, but when I open it the next time it doesn't remember my login. The account is connected to Facebook but it shouldn't matter.

I've looked for the app in the Android TV setting to delete the data/uninstall the app or update but I can't find it. So I really have no idea about what I can do.
