Why does Garmin Connect not let me send an event to my Fenix 6 pro?

Garmin Connect shows my device as connected, but not compatible, so I can't send an event I have created, nor can I send an event I found online and I signed up for. 

All other items (activities) are synchronizing as usual, so bluetooth is working. 

I have upgraded Garmin Connect to its latest version 5.3.2.2 and the software in my watch is 27.00. 

Thanks!
