Unable to upload an activity to garmin connect. Tried manually importing the file .fit using garmin express.
is it lost forever?
got the activity in .fit format
the additional synced hr data from the hrm pro corrupted the fit file
check this file with repaired data from hrm-pro 2022-05-13-12-31-17_with_fixed-synced-hr-data.zip
hr chart from activity without additional synced hr data from hrm-pro
hr chart with repaired synced hr data from hrm-pro
strongly suggest to contact Garmin Support by phone or chat and tell them about this mishap with the hrm-pro
