Unable to unpair Apple Watch from erased iPhone
I forgot to unpair my Apple Watch from my phone before sending it back as a trade in. Phone was completely erased, package, and shipped. I put on my watch on the next morning and it’s asking me to unlock my old iPhone. I tried holding both buttons on the side, but the watch goes off and restarts asking me to open the old iPhone. If anyone have any suggestions, it will be greatly appreciated. Thanks in advance!
