Apple ID and Subscriptions
I have two Apple ID's, my primary ID (call this A) and a much older ID (call this B), I now only use the primary ID. However, some of my subscriptions only appear against Apple ID B, which is annoying and I'd like to move them to Apple ID A.
When I set up my new iPhone 12 I placed my old iPhone 7 Plus next to it and let the old iPhone send the data to the new one.
This results in my primary Apple ID A being the main ID, but for some reason the subscriptions are highlighted against Apple ID B.
How do I get the subscriptions highlighted against Apple ID B moved across to Apple ID A without loosing any and be sure that they will also appear on my other devices, which all use Apple ID A?
