activity didn't sync

Did a ruinning activity earlier today - Ran 18 miles and saved the data to my watch. However, when sync to Garmin Connect on Apple iPhone, the activity does not even show up or appear. It should have sync, but it didnt. Even when I completed the activity it showed me on the watch face the various personal best records I completed, such as, fastest mile, longest run personal best, most distance, most time duration for the run..all of that appeared on the watch face and none of that data sync.

Appreciate any help and how I can view the data from that run activity.
