Cannot Resolve Apple ID Settings Update

I've removed some devices from my Apple Account a few months and ever since I have been getting messages saying "some of my account services will not be be available until I sign in again".

I have logged out and in to my Apple account several times since receiving this message. I have entered my password as well as the PIN numbers for my iPhone and iPad as requested. Not once have I been able to resolve the problem (whatever it is) and I still get the message about updating my settings. I have logged on from all my devices and checked my devices listed in the App& Music stores.

I'm running Catalina and this is the first time I have come across this problem.

I'd be grateful for any thoughts, help or suggestions. Upgrading isn't one I'm afraid.

Thanks and regards,
