@wandio I had the same problem and am really mad. Hopefully someone will have an answer. I lost everything to manage my accounts and business.

My browser just updated (8/25/2023). But I lost all my bookmarks I need to manage my life and business (well over 100). I've used Opera exclusively for over 5 years but didn't have an "account". It has always kept my bookmarks after an update. I'm really mad that this happened and not sure what to do.
