Thank you for responding. I've had the watch for quite a while, but I really don't think I'd even know how to log into something, and I don't think I ever did. The notification said someone was logging in on an Apple watch and using my Apple ID. My watch (which I don't know how to use – can anyone recommend a book?) was sitting in my charger right next to me. I should confess that I'm 75 (the new 74) and a stroke took some of my brain cells – enough that it's noticeable.)
Should I worry about notifications like that?
Thank you to all who respond to idiots like me especially thanks to Ingo2711.
Be Well Everyone
