Charge 6 no longer tracking workouts

[dpatts]

I've had my Charge 6 for about three months. 

I use it to track my workouts – lifting weights in the gym, running, climbing, etc. Today, suddenly all my non-walking activities/workouts started disappearing from the Fitbit app. As I moved back through the weeks, they would briefly appear and disappear. I have now lost weeks of workouts. However, bizarrely, all the walking activities remain!

I went to the gym today, tracked the workout as usual by starting the activity on the watch, completed the workout, and synched the Fitbit with my phone. The workout just disappeared, and Fitbit said I had 0 exercise for the day. I just went for a walk and it logged the walk perfectly.

I have tried updating the Fitbit, restarting the Fitbit, restarting my phone, looking on the browser dashboard on my laptop. Nothing. I just want to log my workouts!

Can anyone help or advise?

Yes the app update resolved the problem with the exercises not being recorded but I am still awaiting the resolution of my floors history being restored. The app is not retaining any floors data and has even deleted nearly all my history going back 8 years. As I can no longer log onto the dashboard on the website how do I access my floors history? 

I have raised numerous cases about this but fitbit just doesn't seem to be doing anything about it.
