In the Garmin Connect Mobile App for Android, whenever I try to look at the activity details since January 1, 2016, I simply get the message: "An error has occurred." and cannot see any activity details at all. If I try to look at older activity details from before that date, most load properly, but others around that date only load partially (all except lap detail) and show the same error message. I have a FR920xt that was recently updated to software version 6.20, and HRM-Run updated to 6.60 on January 5, 2016. However, I have no issues with the Garmin Connect iOS mobile app or online.
