Changed phones from an old Iphone 7 to an Iphone 10x. Migrated everything over and now the all day heart rate just gives me a straight line. I wear a chest strap during running and that records fine, and then after done running it will seem to show up on graph... then stop. Can see the last 4 hours of heart rate on my Fenix 5X, so I know it is recording off the wrist, but not transferring that data to Garmin Connect. It is listed as my primary activity tracker in Garmin Connect. Any ideas?
