hello,
is there a solution for no internet with mobile data (4G) for the app on IOS...
i can only Connect with WIFI...
I had the same problem, and Garmin support advised me to uninstall and reinstall the app, but that didn't solve my problem.
Then I found out that I needed to enable mobile data for the Garmin Connect App:
Settings, Mobile Data, and at the bottom of the page, there's a list of apps.
Make sure that the slider next to Garmin Connect is "on" (by default it is "off", at least on my iPhone)
Hope this helps.
