trying to sign into opera to sync browser for new laptop.

www.sync.opera.com works, but when i click on "turn on sync" and trying to log onto https://auth.opera.com/account/v2/desktop/login, it is just a blank without any reactions!

I tried to login to os account but wipe out all data is not possible. is there another to do it?

Laptop stolen, is there a way to remotely log out of opera and wipe out the data including passwords that is saved in the browser that is lost?

but the opera on the stolen laptop would still work with all my logins, wouldn't it?

How could I sign out of my opera browser account remotely, as my laptop has been stolen. I could find the delet device access for chrome browser but not on my opera browser. It's an urgent need, anyone's help would be appreciated.
