What happen with the books I had downloaded on the Book app?

What Apple did with the books I had downloaded on the Book app?

I had more than half the size of my IPad in books downloaded over years on my IPad. Until last week they where all in the same place, my Book app.

Today (2020-27-02) all is gone! I noticed that Apple started placing apps on cloud without my authorization, my husband saw the same over his IPhone. But this went far enough!!!

All my PDFs books collected during years!!!

Does anyone can explain what Apple did WITHOUT MY CONSENT?

For what I understand, the virtual space inside MY IPad belongs to me, and not to Apple, so they could not go and just delete my stuff... I’m really mad 😡
