Noticed one very specific bug. When going to any activity (Run for example), press start and go to the next screen (to check today's Garmin suggestion), and then go back to the main screen (watchface) - it is completely black. Only going to any other menu and then back returns normal watchface. This bug appears only during the following conditions - if you add TWO CUSTOM DATASCREENS from the IQ store to any of sport application and if you have CUSTOM WATCHFACE. But this is normal setup for me and experience this problem very often. Any other saw this bug?
