After deleting a bunch of movies in Infuse (latest version) on my 256GB iPad Pro 10.5 running iPadOS 16, the movies are gone, but the space is not released. It showed 77GB of “Other System Data”.
I then went into Settings → General → iPad Storage and deleted the Infuse app + all data, which still had another 70GB of movies in it. The app and the data is gone, but now “Other System Data” swelled to 148GB.
Rebooting the iPad multiple times did not allow me to recover that space.
Any other ideas apart from resetting and restoring from backup?
