Hi @Rel, and welcome.
There are many complications to ebook readers. The process of accessing content is complex and prone to failure. For a start, could you outline the process by which you access ebooks from your library?
You might find some answers in this thread:
I’ve never borrowed an ebook from a library. Nearly all of my reading is in the public domain. There’s more than a lifetime’s reading, freely available from sites such as:
Project Gutenberg’s Australian incarnation: http://gutenberg.net.au/
The Internet Archive: https://archive.org/
and the Open Library: https://openlibrary.org/
For the record, my reader is a Kobo Clara HD. I’ve never tried the options built in to the reader for purchasing books. After figuring out how to download books to my PC, then copy them to my reader, there hasn’t been a hitch. Yet.
