Hi,
I have Fenix 7X Pro, Firmware 17.20 stable (no beta) and since update I continuously experience issue with Calendar glance.
When I open calendar glance it just blinks and crashes.
You can see it at photos.google.com/.../AF1QipOmqxMRuHXHNRDM0j49_UQ-r37mO3j1Ho84tfCK
Restart of the watch solves the problem but it is extremely annoying.
I think it is related to daily training recommendations. They also don't appear when I select Run. Normally daily recommendation is there but when this bug is present then they aren't there.
The same issue was reported for 17.10 Beta (https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/fenix-7-series/366518/fenix-7-pro-system-software-17-10---problem-with-calendar-opening) but it looks like it was not solved properly.
