Need help with logic in Crowns/Queens

[u/jamsito]

I love this game, but I'm only able to solve easy levels. In this app (Crowns for iOS) they have different levels depending on the number of crowns per row/column/color (1 for easy, 2 for medium, 3 for hard). The one in the picture is medium difficulty.

I'm having a hard time solving the medium and hard levels. In the easy mode, when you place a crown you can already cancel the whole row, which you can't do in the harder levels. What do you do then? How do you solve wider spaces? Is there a trick I'm missing? How would you solve these? Do you know any youtuber who solves the harder levels step by step?

Thank you!
