I just received an Apple Watch 2. Can't get it to pair with my phone. Updated iOS on phone. Restarted phone. Reset Watch. Bluetooth is on. Will not pair with camera. Phone recognizes number of Watch when pairing manually, but does not give me opportunity to enter 6 digit code, sometimes because Watch won't display code, sometimes because phone tells me pairing has failed before I can enter 6 digit code. Any suggestions?
