Heart rate data suddenly not synching from Fitbit

[Bjdnh]

All of the sudden no heart rate data.  And this is the foundation for relative effort and fitness. I tried to manually upload the file but Strava would not accept a duplicate file. Any ideas?

 Mine too. Showing it with the fitbit one. Exercise on the 1st September

Same issue - no heart rate data transferred from FitBit to Strava for the past two days. It worked fine on 1st September (and before that) but not the past two days. The heart rate data is in the FitBit App, but did not transfer. I tried deleting the automatically transferred data in Strava and manually uploading the tcx file into Strava. Same result.

Help please - I need this.

I've had the same thing happen. It worked on August 31, broken on September 2 and today. Fitbit app shows heart rate for the whole route.
