Since update to Garmin Express 6.19.2.0, when my watch is connected to my PC it keeps rebooting itself. Everything else seems to work normally. I have already tried the usual reboots, uninstall and reinstall Garmin Express. Any ideas / suggestions? Are there any cache / temporary files that may be stuck I can delete? Watch stays on if connected to the PC without Garmin Express running, and I can see it and its folders in Windows Explorer. Thanks.
