We used to be able to connect our Garmin Descent G1s by USB to Windows computer, and download the dives into Subsurface.
It seems to have stopped working since a software update. Looking into the Garmin USB drive there are no .fit files at all in the \activity folder although dives show up on the G1s, Connect & Dive apps, looked into all the other folders but not seeing corresponding .fit files for the dives.
Thanks for any help or suggestions.
