To get everything to work, after a few days of all the mentioned problems I did this: reset everything - Factory reset from the menu. I then signed in, re-linked my key and made sure all the disabled services were re-enabled. This got rid of the login prompt and everything is working BUT I guess this fully cleared my profile because I needed to redo my radio station list, navigation favorites (had disappeared before the reset), sound settings, lighting settings, door lock and entry settings ... full restart like new. I like that because I got reacquainted with all the possibilities and functions, but took way to much time.
