Apple Watch Ultra 2 Locks while on wrist
So I just received my apple watch ultra 2 and it keeps locking whenever I move my wrist. I have the milanese loop band and have it as tight as I can possibly get it. I've tried to turn the wrist detection on and off and it still locks even if I'm wearing it. It is running watchOS 11 and my phone is running iOS 18. Any ideas on how to fix this would be great.
