Hello everyone,
I'm writing because I recently bought a Kindle (2019 edition) and I linked it to my amazon account and then, other than purchasing books from amazon, I filled it up with pdf files I needed.
Then, some days ago, I lent it to my brother and told him He could link it to his amazon account if he wanted to purchase other books. What I didn't know is that, by doing so, I lost all my pdf files and even by linking the kindle back to my account, only the books I purchased from amazon were restored, not the pdf files.
What I would like to ask you is if there is a way to restore thise files, because I quite need them.
Thank you all for your help, I hope I can solve this.
