WatchOS 4 encountered problems

Hello! I believed that WatchOS4 will work with iOS 10 but I fooled myself in believing it. I downgraded from iOS 11 to iOS 10.3.3 and reseted my Apple Watch hoping it would work. The pairing does not work when running iOS 10 so I switched back to 11. The only way to make the watch work is with iOS 11 which is gorgeous but unstable at the moment. This is the interesting life of a Apple Developer!
