Won't connect

I struggled with a similar problem and eventually succeeded after two days of hard struggle. In my case it was possible to change the region in the iPhone and Apple Watch. The Region has been changed to both the United States, the English language. On the watch did not logged to ICloud, installed the installation of manual, set a tuple code, skipped the rest of the options like adding Apple Pay etc. The waiting room to the end of the installation and it was successful. The installation time has also been fixed from two hours to 20 minutes.

Thanks Matt. Both device have been preset to same region (US). What is a 'tuple' code? I have noticed the typical install screen of asking where to install profile (watch or phone) is missing
