Adblocking in Opera

A Former User

Hi, I just want to like Opera on desktop. But I've run into an issue every now and then.
The moment I enable the native ad-blocking in Opera, I always delete the pre-installed execptions like Google, Facebook, Baidu, Yandex. I mean, it's ok, they are excluded on the first run. I know that.

But they very often show up on a new start again. I haven't found any pattern for this, but in my experience it's either after a complete launch of the computer or after every update to a new version of Opera.

You may delete the exceptions of course, but why are the settings that you've decided to have are not respected? Any explanation for that?
