Just saw that if you choose to have Apple delete little used apps, it can’t restore them if they’re no longer in the App Store. That’s happened to the Lightning DS that was on my iPad. Can’t restore it now. I tried using Lumin (which had worked years ago) to control my Aries Femto. While Lumin recognizes the Aries and the library, once you start playing the controls play controls didn’t work on my iPad. Only way I found to stop the music was to delete the queue.
On the other hand, gapless playing works.
I’ll see if I backed up my iPad and see if I can restore Lightning.
I use Room typically so not a major problem.
