Hi,
since the installation of version 22.22 last night, I'm having the blue triangle of death whenever I start an activity.
As soon as I start an activity, the screen will turn completely black and the watch becomes unresponsive. Pushing the upper left button for a long time (+15 seconds) will give me the frozen, blue triangle of death. After a couple of minutes, the triangle disappears and the watch returns to it's normal watchface and the activity is aborted.
I did not experience this issue a few weeks ago when it was mentionned by other users.
FYI: my watch is not linked to a phone, I use a USB cable and Garmin Express to transfer my data.
