Watching ads for hints? – Alpha Omega Review

I LOVE this game. I bought the almost full version (all & future packs, not the one with themes, etc.). I've noticed that I can no longer watch an ad for a hint like I used to. I didn't use it super frequently, but it was nice when I had been stuck for a while. I can't do that anymore. I don't want to pay for hints, because if I did, I would've just bought the full version. Why can I no longer choose to watch an ad and get a hint?
