sync issues

Hi

The Garmin Express (version 6.19.0.0) on my Macbook pro(Mojave version 10.14.6) does not recognize Forerunner225 when connected via USB port, while the Forerunner has no problem charging.

It has been working fine until Software Update Available showed up in Garmin Express. When I click "Install", it says "Plug In Your Device" but after hours of "Searching for device..." it cannot recognize Forerunner225 connected.

Thanks in advance!
