Are you saying that the .FIT file isn't saved, or that you don't see the data on Garmin Connect? I believe that you'll only see data in Garmin Connect if the app has been submitted to the store (the .iq you upload has data that tells Garmin Connect how to present the data).
Hi Travis, I am not seeing either. The device (Vivoactive) has no new activity in the device history, so nothing syncs to Connect.
I added logging to all the ActivityRecording and FitContributor lines, and no errors. I also side loaded one of my established apps (hSport) and got a successful recording (it doesn’t use FitContributor).
