I have added a training plan to my Training Calendar and scheduled it a workout every other day.
If I edit an upcoming workout in GC, save it and then sync the watch, the workout is not updated on the device. I purposedly renamed the workout (added the letter N at the end of the name) to check if it is updated, and it is not.
I tried reconnecting the watch, syncing several times etc. The only effective workaround that I found is to shift the entire training plan back and forth by one day. After the initial shift, that particular workout is immediately updated on the watch.
I have a 7X set as Primary Wearable and Primary Training Device, software version is 11.28.
Are you guys having the same issue? Perhaps an option to manually force Calendar update would help, idk.
