Doesn’t work on WatchOS 5

My favorite midi app. I used this to send midi commands from my Apple Watch to my DAW on my laptop via OSC in live performance. Worked very well until I updated my watchOS. Wish I knew that the app wasn’t compatible on watch. It still opens fine on phone.

Given it’s been 3 years done creation and update of the app, I doubt there will be a fix. Also, the developers site is still up but extremely difficult to leave a request for update there. ?!?!?!?!
