I know there have been issues recently but while I'm able upload from my 310xt OK now I can't from the Garmin Swim.
The files get from the watch to the Mac OK, there are 4 files sat in the PendingSyncUploads/Activities file and 1 in the PendingSyncUploads/FIT_TYPE_4 file but none are getting to Garmin Connect.
Currently on Garmin Express 3.2.28.0 and Yosemite 10.10.1
Any ideas?
