Apple Watch 3 will not connect to iPhone
New Apple Watch 3 will not connect to iPhone 6 which is using iOS 12.5. The prompt to start pairing devices come up on watch and iPhone. When we start the process, we enter the countries and language we get as far as the prompt on the iPhone to enter the 6 digit verification code. The 6 digit code does not appear on the Watch. The Watch remains with the 'Apple Watch 02980' pairing number. We have tried the automatic pairing but that does not work either. We have tried numerous trouble shooting methods but nothing has worked as yet.
Any suggestions???
iPhone 6, iOS 10
