My Forerunner 965 just updated with the 22.22 software update and now the screen lags when I try to use it.
When I press the down button or long press something like the weather, the watch freezes, noticeable by the seconds indicator no longer incrementing and buttons no longer working, and it takes around 8 seconds before the widgets are displayed and the inputs catch up.
Afterwards navigating around works mostly as expected. Although sometimes trying to navigate back also freezes.
I've tried turning the watch off and back on again, resetting it, reinstalling the software update, and doing a full factory reset.
I had no issues before the update.
