Play AI Bug

There seems to be a bug when selecting to Play AI. Sometimes it works, but more than half of the time, I end up a game where I’m playing both the black and white pieces. I end up having to delete the game and start a new one over and over until the AI finally kicks in. It’s a nice app when it works, but it doesn’t always work as expected.

Problems not beginner friendly

I wanted to use the problems to gain a good foundation as a beginner. The first problem I tried labeled “Elementary” was over my head, had no explanatory tips, and when researched in Gemini AI, said requires reading multiple moves ahead and knowing a tactical concept of crane’s nest tesuji. Things I hope to get to someday, but not where I am now. I see only frustration ahead with the problems in this set for a total beginner.
