I don't know why this happens but t is getting quite annoying. As you can see in this image, it says something went wrong. Synchronization has stopped because of an error. It wants me to sign in...yet again. When I try signing in it tells me i have wrong password...but when I sign in on the website, my password is the same and signs me right in. i have changed my password numerous times. Works on website but not for synchronization. If I try to use the quick QR sync the Opera Browser completely crashes down and re-opens saying something about it has recovered from a crash.
