Currently on FW version 13.22. Most of the activities I've been doing on the watch involve workouts that I've created on Garmin Connect web/mobile and sent to my watch. I've noticed that some of the workouts that I've sent to my watch previously and run previously are no longer there the next time I try to do that workout. As a result, I've had to resend the same workout to my watch multiple times.
I have 8 running, 2 strength training, and 1 cycling workout, if that is relevant information.
