@leocg thats a good point actually. I used 2 different passwords to sign in each time, but only one of them alowd me to sync.....odd. but yes it's working now so all good.
@monkeychime Hi ! Yes I had that issue because I used the dark background on all sites and had the "inforce it on websites" case ticked. I tried to put it on "Use the system background colors" and unticked the forcing, refreshed the connection page and it worked. Not saying it was 100% that but well, trying can't hurt. Hope this helps !
@levak69 As said, go to sync.opera.com and click on the reset passphrase link. After have confirmed it (remember that all your data will be removed from sync servers), logout from Sync service in Opera, login again and go to opera://settings/syncSetup to change or disable synchronization passphrase.
@oliaiden Opera imports data from the default browser during the installation process.
If you don't want that to happen, click on options and uncheck the option.
