Also I have been careful to uncheck at Settings cog > General Settings > both "Always keep Garmin Express running in the background" and "Automatically launch Garmin Express when a Garmin device is connected" and reboot afterwards as advised in the express.exe thread here. Again, they are unchecked. In the same location, under Advanced, "Garmin Connect Authentication Domain" says, correctly, United States. Update Schedule has been changed to Never. Proxy Settings are on the default Auto.
