Since I have the Venu 3, it is not able to broadcast HR to 3rd party app (in particular Skimble Workout Trainer).
Either it doesn't broadcast at all, either it happens once in a while and not regularly.
I've requested debug to the 3rd party app supplier, but it seems related to compatibility and connectivity issue.
Any clue what information do you need to identify the issue I am getting?
I've just updated to last SW version 10.20, without any improvement
