How do I know if my iOS Safari content blocker is

This question already has an answer here:

Is there an iOS API that would tell me if my content blocker for Safari is enabled? Or do I have to resort to some kind of heuristics if I want to know that?

Have been wondering the same question and eventually came up with this method: break the structure of your .json file and see if you get an error in debuger. If you do - everything is fine and you should revert your .json to the normal state and carry on.
