Thank you for replying...I really appreciate it

. Are you sure it supports the 2019 Oasis? When I connect my new Oasis with a USB, Calibre won't recognize it. I looked online and it says that Calibre supports the 2017 Oasis, but not the 2019 Oasis. I updated my Calibre to 3.46.0. Is there a more recent version. Thanks again for your help!
