I know Strength Trainer isn’t really good at detecting the spikes in HR, but this is even worse:

Here’s a 14-second-long GIF (the forum didn’t allow uploading a movie file):

Right now, during an exercise, the heart rate number doesn’t update.

Heart rate is correctly registered when I finish the workout, so this is likely just a display bug, but it’s really annoying.

Doesn’t happen always.
