Animal Farm. Educational Games

My daughter loved this game. When we first downloaded it there were ads after playing an animal but nothing terrible and all animals were available. All of the sudden one day everything but one or two animals was locked. I spent hours playing and earning cards to unlock all the animals for her again. A few weeks later another update and everything is locked again. This time it seems only some animals can be unlocked unless you pay to open premium cards. My daughter is 3 and doesn’t understand why she can’t do things she could do before and quite frankly as an adult I don’t understand it either. Who wants to even spend time opening up areas if at random they will be relocked?

This game has way too many ads for a children's game. They are constantly in the top corner of the game. Not much to the gameplay which world be ok for a child maybe but it feels like the sole purpose is to run ads.
