Accepted the new Copilot update from Mac, iPhone, and iPhone and lost my entire Library

Greetings, all. I just accepted the install for a new Copilot update for my three Apple devices, and lost all pages in my Copilot Library. Microsoft promotes the sustainability of the Library storage as their AI continues to evolve and improve. But, really not happy that I've lost all of the documents where my edits to the pages were not covered in a chat conversation. Has anyone else experienced this problem and hopefully found solutions to retrieve the lost pages? I've tried to use Copilot to solve this problem without any success. Thanks, all.
