Garmin Express won't recognise my garmin Marq Adventurer gen 2
Do a full uninstall and reinstall of Garmin Express. If you have access to another computer, see if you have the same issue between your watch and the computer using any other computer so you can rule out your own computer and more clearly define if the issue is specifically your watch going sideways.
When testing, check the computer to see whether it shows your watch connected or not. If your watch is not transitioning properly for the connection to be seen, Garmin Express is not going to have the chance to see it.
If you believe the issue is your watch vs. the computer(s) tested, fully reset your watch to defaults then test again.
