Ran 5 miles today and the run is in my Fenix 8 history but won't sync to the app

I have a new fenix 8 Pro - 51mm. I just did a PR training run but it won't appear in the app. I've dug around on this forum but there doesn't seem to be a way with Mac OSX to manually get it into the app. I can see all the training data for the run on the watch. This is a real deal-breaker for me: i just moved from Polar and I now regret it. Any way I can get this run into the app?
