I have just bought a Forerunner 235 and am having difficulties with the software updates via Garmin Express. In fact, it has never worked despite multiple reinstalls.
When I connect the watch, GE says there are 5 updates available. After an attempt to install, the program keeps asking to re-authenticate. This is a never-ending loop. Extremely frustrating. I am using Windows 10.
Further to this, the watch never syncs with my android phone. It gets stuck every time and errors.
Please help.
