No errors were reported, and the G2 did indicate that a device was connected during the download attempt, but Subsurface kept reporting that no new dives were found. Restarting the phone didn't make any difference.

So I'm not sure if the app wasn't seeing the new dive, or for some reason wasn't considering it to be a valid item and consequently skipping it. The only difference I can think of from previous dives, which were downloaded successfully, is that this one was had the G2 set to Sidemount mode.

Subsurface-mobile always creates a log file and libdivecomputer log file. After an unsuccessful attempt, simply go to the About page, click the button and then paste the log files into an email message.

No, I doubt it's sidemount related. More likely a BLE issue.

See above. Please try a BLE download on the phone and then send the log files
