Number of phone notifications on the watch face widget stays stuck forever until I "refresh" screen by clicking UP or DOWN button. Then it sets itself to a correct number of notifications that I actually have currently on my phone.
For example, I dismissed a notification on the phone and then after maybe an hour, on the watch home screen it still showed I have 1 notification but in reality I didn't because I dismissed it long time ago. Then I clicked DOWN button and it immediately refreshed to 0. Also, It wasn't a one-time event, it's a persistent bug.
