Whoop HR during Strength training doesn’t move

Hey team,

more than a week ago you made a firmware update that finally made the strength trainer on pair with the apple watch HR during lifting session.

You registered the sudden spikes in the HR, like never before. I was really happy. However there was a recent update, and not just that everything went back to how it was before.

HR during my last session didn’t even move.

What’s going on?
