How do you stop Strava writing back to Fitbit app? Using Sense 2

[Lashes77]

My activities used to just write to Strava from Fitbit. 
Now they are all writing back again after being copied from Fitbit. So duplicates. 
REALLY FRUSTRATING 

Support told me they “ can’t help as third party app’. 

Also have a day where steps suddenly duplicated twice at 7pm, but show between midnight and 1am. So have three times the steps. 
support couldn’t  help. 

So over this crap support. They raise a case and no one replies.

Welcome back to the community, @Lashes77.

Thanks for letting me know about this situation in regards to the steps duplication using your Sense 2 and Strava.

I was able to confirm support has helped you already and they'll get in touch with you once again since the case was escalated. I'd also recommend you to contact Strava support, so they can also help you since it could be a situation in their end.

No…… Support have not resolved either issue. They “ escalated” it. I received an email asking me to check my app was up to date ( it is). 
That was all that was suggested. So no…….very much open issues.

“Escalated support” advised they cannot fix it. So essentially my data is incorrect. I have sent a complaint email as there are too many bugs since I transferred to a google account/ recently which aren’t being fixed. Disappointingly any complaints on here are deleted.
