@leocg I use just regular Opera. Synchronisation must been enabled, but I’m not sure. There were my bookmarks, passwords etc but now there is nothing sync.opera.com

I reinstalled windows 10 on pc and all my data from Opera just gone. I don’t have saved passwords, bookmarks etc. I tried synchronise with my account but nothing happened. I exported my personal data from Opera. How can I import these data in my browser? (Sorry for my English)
