Question: Check all of your Apple IDs?
I was surprised to read that at this link:- https://support.apple.com/en-gb/ht201382. (Item 3)
I've been using Apple products for many years now and have only ever had one Apple ID.
Why would anyone need MORE than one?
I've not considered this matter before. Am I simply naive?
