Not really sure what I could have titled this, sorry lol.

When you double-click, it will sometimes automatically match the pair. As you can see in the video, it doesn't always do it, but I double-clicked each time regardless.

Also, although it's not the focus of this topic, someone else mentioned the game not letting you play it even after 30 mins. Just wanted to point out that happens to me as well.

I reported this four months ago and didn't get any responds

oops, didn't see that! considering there was no response to yours or mine I doubt it will be fixed.
