What the heck? I go to install an app on my Apple Watch. The physical watch pops up with "Apple Account Verification". Ok, I tap on the Settings button as it asks. Then it says to Sign In to Complete Purchase. In the upper right of the watch screen, it has a Sign In button. I tap it, and it just spins! No keyboard, no popup on my paired phone....nothing! How the hell am I supposed to log in like it's asking??? Thanks!
