Problem: iWatch5 is no longer connected/paired with iPhone12 since some updates.

Hi Everyone,

I have tried many ways but unsuccess.

• iWatchOS 7.3.3 can't update to 7.6... the latest.
• iPhone has Watch App installed but keep asking to pair with iWatch.
• I couldn't pair; the viewfinder camera could not detect iWatch.
• Can't unpair, can't update, battery-less than 5 hours
• Finally, how can the top quality device face this difficulty?

Would you please advise if you have similar problem before! Thank you!
