This message appeared in Settings a while ago. It was like this on 11.1, and if I clicked the button, I just got endless spinning dots and had to force close settings. I figured if I updated to 11.2 the issue would go away. It still does the same thing. As far as I can tell, everything works fine, just unlocked my Mac with watch, can view other AppleID stuff, find my works. Anyone else have this weird issue?
