Not a big deal but I thought I’d mention it.
iPad Air 4 iOS 14.7.1 256GB

I had a solo piano part, but then decided to add a xylophone and transfer the piano treble clef notes to it via cut and paste. So far so good. I then deleted the whole piano part, but the bass clef still continued to play. I double checked I’d removed the piano, and it didn’t show in the Play section.
I tapped the arrow at the very top left of the screen to go back to the “hub” and re-selected the project, after which it played back perfectly, with no hint of a hidden piano part.
Maybe this is a quirk of iOS and caching or something?
Anyway, no big deal - love the iPad version!
