Hi
The following steps may help:
Check that Theatre Mode / Cinema Mode is not enabled on your Apple Watch:
Check your Wake Screen settings:
- On your iPhone, in the Watch app, go to: My Watch (tab) > General > Wake Screen > check that Wake Screen on Wrist Raise is enabled.
Check your watch orientation settings (which tell your Apple Watch which way up and which way around you are wearing it):
- On your iPhone, in the Watch app, go to: My Watch > General > Watch Orientation.
