I have not updated or used Garmin Express in over a year now. I do own quite a few Garmin products, ranging from watches to Varia lights. But have not connected them to Garmin Express for a long time.
I recently got the FR935 and set it up without Garmin Express and have not had any issues.
What exactly is the point of Garmin Express if you can download and install software updates without it. Am I missing something?
