The same apps I always used no longer work because of OS requirements. The “download older version” feature is extremely hit and miss (mostly miss).
The device works fine and is functionally useless because Apple said so. That’s not cool with me. Android might be just as bad, I don’t know — I’m sticking with FOSS mostly these days and just don’t have a working tablet anymore.
Just solved an issue with transcoding where I had to delete the codec. It redownloads on server launch so was an easy fix.
