Incorrect Apple ID for Watch
So I had a problem with my phone and ended up taking it to the store to get it reset. Now the phone is fine and I got all of my data back but now I am trying to pair my series 6 apple watch to it again. When I go through the pairing process it tells me my watch needs a software update and to do that I need to put in my apple id and password. I do so and it kept saying incorrect password (I know for a fact it was not). Despite that, I still go to my phone setting and I change my apple ID password (I have since done this 3 times). Seconds after changing my Apple ID password, and verifying it was working by logging into iCloud, the watch app still tells me the apple ID is incorrect. I don't know what to do anymore but it keeps saying "Apple ID incorrect, cannot use this apple id to unlock this watch". I am the only owner this watch has ever had so it was never paired to someone else, only me. Please help :(
