I use Ismoothrun as running app on my AppleWatch because garmin does not support Apple watch (what a big mistake since i am using Garmin apps now less and less). The iSmoothrun app supports the connection and exchange to Garmin connect once the Ismooth run results are loaded on the iphone. However since a few months the sync process gets a 402 error message just for the sync with Garmin Connect, (with other apps like runkeeper, strava, and even dropbox it works fine). Anyone having the same problem? is a restrictions on the side of Garmin or rather a problem on the ismoothrun app??
