Garmin explore iOS app not adding a recent activity

I have a gpsmap 66st and a recent activity has not shown up in the Garmin explore app after syncing my iPhone 7.  I’ve shutdown and restarted both the phone and gps and have synced each time, but no luck.  I have 3 prior activities in the app, so I have no idea what I am doing wrong this time.  Both my phone and the gps are using the most recent updates.  please help.  If more info is needed, please let me know.  And I apologize if this question has been asked before.

Thank you.
