Pages docs gone from iPad

Hello,

I have been storing hundreds of Pages documents in my iPad over the past

few years and recently I noticed several of them have randomly disappeared.

i didn’t update the iPad or the Pages app (that last one I’m not 100% sure), but I did turn on the option of saving the pages documents to iCloud Drive, which apparently made my iPhone and iPad files sync and, in the process, at least 150 of my files disappeared. I already searched iCloud and tried “restore recently deleted files”, nothing shows up.

Can anybody help?

thank you!!
