DJM Rec Issue - Recordings stop

I've purchased the DJM recording app and at first it was working perfectly. Now almost every time my recordings will automatically stop a few minutes in (sigh). I'm hoping there's a fix, because I am losing my mind.

-I've tried doing a full reset of the settings. No change.

setup:

2x XDJ-1000mk2

DJM-750mk2

All have most recent firmware.

Thank you!
