Data sync with Garmin Dive app (android)

Question

I have a Garmin Descent MK2i and have been using it for sometime now. 
 There are instances where the dive computer logs the dive, but doesn't sync it with the Garmin Dive app. 
 Has anyone faced the issue before? What can I do to solve it?

Most likely the .FIT file on your device is corrupt. There are bugs in the device system software which appear to cause intermittent file corruption. Unfortunately Garmin support isn't very interested in fixing the root causes so we just live with it. 
 Try syncing over a USB cable with Garmin Express but most likely it still won't work. So you can try to repair it with other software.
