Hi there!
I exported my Garmin calendar some time ago and it was not syncing my changes with Google Calendar. So I wanted to look inside of Garmin Connect if everything is ok with the export link, but the small arrow that allowed me to export the calendar is gone. I am pretty sure it was in the right upper corner. Is it really gone? Has it moved somewhere else, or am I blind? See screenshot (in German).
The problem with Google seems not related to this, by the way. The new trainings are there if I open the (earlier) exported link with some other calendar software. So I will probably just have to wait a little more until Google syncs with Garmin again.
