How to resolve Apple Account login errors on iPhone after pairing my Apple Watch?
Check failure. An unknown error has occurred. They worked perfectly on my iPhone 14 Pro. Yesterday I gave my Apple Watch to my wife, created a pair on her iPhone and problems began. I can't log in to my apple account. I tried many different options, but I still couldn't find a solution. Help
