Uh oh. I goofed. I assumed you were an iOS alpha (a pre-beta release) tester. The alpha test for iOS involved use of Test Flight and I was oblivious that Singular Sound had made the beta available on the App Store. I gave you feedback based on my bad assumption.
I’m in the process of editing my earlier post replying to you and we can give it another try. In the meantime, remove Test Flight from your device and then download the MM app again (sorry, 
)
