In Garmin Connect, I can update FTP (navigation path: select device > user settings > power zones > functional threshold power > save) but the updated FTP is not displayed in training stats (navigation path: More > Performance Stats > Functional Threshold Power). I am using a Forerunner 935, Garmin Connect 4.25.2 and iOS 13.3. I have checked for and installed all updates. I have tried restarting and syncing all devices. Garmin support is unable to provide a resolution.
