I have an iPhone that has a different Apple ID from the ID that I have on my other devices. How do I change the ID it to the ID I have on the other devices?
I have several iOS devices (2 iPhones, 2 iPads, 1 HomePod, 2 iwatches. All use the same Apple ID except one of the iphones. I was forced to change its ID to use the i watch walkie talkie app. I don't use the app and want to change my apple ID for that device back to the previous ID so that all my iOS devices will have the same ID. How do I do it?
