Fitbit app won't register excersise correctly

[Woodieee]

I've had my charge 3 for a couple of months and it's worked great. However lately it won't register my excersise correctly in the app. I mostly do interval runnings on treadmill. If the check the minister during running it shows high heart rates while running and lower during rest. But when I check the app the stats don't correlate at all. On the dashboard on the website it looks the way it should. My app is up to date and everything else seems to be working.

On your dashboard things look fine? Where do RT not look fine?

The app shows incorrect stats whereas the website shows correct information about heart rate and distance. Both the information about maxiumum and average heart rate and the graphs are wrong in the app. It's not every time but it has happened enough to be fairly annoying!

Interesting since both get their data from the same source.
