Unable to pair with my phone, screen has the Apple logo with a circle surrounding of slashes
I had to send my old phone back but neglected to unpaid my watch. Now I'm unable to pair my watch with my current phone. I'm new to Apple watch. My watch screen has the Apple logo with a circle surrounding of slashes. What do I do next to reset it?
