Cannot recover deleted PDF with markups from Books on iPad
I downloaded a document I was working on as a PDF to my iPad, and opened it in the Books app. I then used the markup tools to highlight and make notes to myself on it.
Stupidly, I thought I was done and didn't need this file anymore, so I deleted it, to avoid mixing it up with other versions on my device. This was just a few days ago.
Now I need it back, specifically with my markups. I cannot find it anywhere. It's not in my recently deleted folder when I opened up my iCloud in a browser. It's not in my Recently Deleted folder in Files. I can't find anything similar to Recently Deleted in the Books app. And most of the advice I see along these lines says "Just go back to the Bookstore and re-download your purchase." Well it wasn't a purchase, it was my own document.
Is there really no way I can get this back? There's no way at all to get back something I removed from the Books app short of re-downloading a purchase???
(Maybe this was dumb of me to mark up a PDF in Books. Doesn't matter now, that ship has sailed.)
This is an iPad running OS 26.5
iPad (10th generation)
