BUG Tracker+/Mini stop receiving notes via MIDI after some random time

The notes that should come in, control a synth engine on each tracker, sequencer is Beatstep or MPK mini plus but this doesn’t really matter.

As long as the sequencer is playing, I did not notice an instant drop of MIDI notes input.
If the sequencer is stopped it takes a random amount of time to stop accepting note input.
After that, both trackers still receiving clock and transport but no notes. (As I can’t get cc working, I can not “test” for this yet)

Without powercycling the devices, there seems no way to get out of this broken state, I’ve tested
numerous approaches:
loading another project
disable/reset/re-enable midi
change channels
reseat cabling

Both tracker are on the latest firmware, this whole MIDI implementation is so messed up and this feels more and more like a beta test than a notable experience.

Not able to sync, no reliable note input..

This is clearly a bug and should be looked into by Polyend people and should have been catched during testing in the first place.
