Hi,
I have such problem that I cannot set new FTP values into my garmin account it always revert to old values.
My primary training device set is edge 840, primary wearable is forerunner 970.
New ftp detection is set on both but I never accept new suggested values, I always do separate FTP test on edge.
The problem is no matter if I set new FTP on garmin connect web, or garmin connect android app, after a day or two I power up the edge and I see my old FTP number - this is so frustrating because I correct this already fifth time.
I have checked on other connected sites like trainingpeaks but there is correct new ftp number entered there.
