I use a Forerunner 745 and Edge 840, and have recently enabled beta mode in the Garmin iPhone app.
It appears that activities are not syncing across devices and performance metrics (e.g., training load) don’t consider all of my activities. You can see the steady downtrend in training load in the middle of the last month in spite of completing activities on those days. The same occurred after a big cycle yesterday with my acute load being low today.
Has anyone had similar issues and found a solution?
