Is anyone else having issues with the weather app? It displays on the watchface but spins and spins when pressed and returns to the watchface after a few seconds.
Same thing happened to me, so I power cycled my Watch, and after about 10 minutes weather came back up. It didn't work immediately after powering back on though. Maybe just give it time and it'll work soon for you.
Watch face 'complication' and weather app both work fine now.
