Sorry for the delay. It's been a crazy couple of weeks.
I do have 'prevent delay when starting metronome' selected. 

If my surface has been asleep, I turn it on, and plug in my headphones. If Mobilesheets is in the background when I plug my headphones in, the metronome will glitch when I activate Mobilesheets and start practicing.

Here's a screen recording of what it looks like. (it didn't record the audio though but it's usually a single click).
