The notifications stay visible until I dismiss them, last week I went to sleep leaving a whatsapp notification and when I woke up it was still visible in the watch instead of the hour.
Is there a way to hide them automatically if ignored for a few minutes?
The icon on the top left your screen shows me that quiet time is enabled. By default if you hold down the left button on a watch face, it’ll turn on and turn off quiet time (you can check to see if it’s on by going to settings and then quiet time). But even with quiet time on there is a setting that you can automatically dismiss notifications when quiet time is on.
