Edit: for now after additional reboot it started working again... Not sure for how long....
Hello!
Have you tried restarting the watch yet? I updated to 14.15 this morning and am unable to duplicate the issue. I also notice that you have a bit of a flicker in the screens that shouldn't be there and and a restart might resolve that as well.
Same for me after the update. But no problems since rebooting the watch.
