MainStage 3.6 play button stops midi clock for external devices

Hi, my setup involves running a midi app (Genome Midi Sequencer) on my iPad, which listens to the midi clock sent by MainStage. Under 3.5 pressing play in MainStage would start the sequencer app on the iPad with the beat synced to the MainStage clock. However... under 3.6 pressing play actually stops MainStage from sending the midi clock data to the iPad, like the behaviour is reversed. (The iPad starts receiving clock again when play in MainStage is stopped)

I've been unsuccessful in finding a solution for this. Leaving 3.6 unusable for me. Does anyone have a solution? Is this a known issue? I'm of course happy to provide more details if necessary
