When i cycle on Zwift, i have my trainer and HR in parallel connected to Zwift and to my FR945 to record the activity on the watch. This is for having proper training load and will always create two activities in GC: One coming from Zwift, the other one recorded by the FR945 and synced over the air. So far so good. I just delete the one from the watch in GC and keep the one from Zwift which has also elevation data.
Now, if i connect the watch via USB it will re-sync all the indoor cycling activities i already deleted. Not a big problem as well, i search them and delete again. Think the job is done, but no: Everytime i connect the FR945 via USB it will re-sync all the activities from the watch which i have deleted already before.
Is there a setting i am not aware of, or is this a design flaw in synchronisation between GC and FR945 (could be with other monitors as well)?
