Yesterday I tried to sync my watch by WiFi, but nothing appeared in the Garmin cloud, even though the watch said it had synced successfully.
I eventually found a small popup in Connect web saying I had to confirm some updated Global Data Protection Regulation settings to allow Garmin to store my personal data.
When I synced again, I finally got some data (like steps) across. The watch did however refuse to transmit heart rate data and sleep data again, so those remained empty for the day.
I also tried to sync by bluetooth via the phone, and by cable to Garmin Express, but the data was still lost.
Is there a way to force the watch to sync the missing data again, as I can still see it in the watch?
