The last few betas have been very stable for me on my iPad mini A17 and M1 iPad Pro, but the only app I've encountered that has had any major issues is Band-in-a-Box. I'm sure it's the most recent version as I allow it to automatically update all apps.

I hope this will be fixed soon, or at least soon after the iPadOS 26 release. It's a cool tool to use on my iPad Pro when I practice my piano.
