content: Loved it until pro change. Used this app a lot while studying for myself  with my 7 yr old during pandemic homeschooling. We had several trees unlocked that she liked and saved up the focus credits to unlock but after the change to the new pro settings all of the saved up trees are gone. Thanks for the credits back I guess but theres no point to them if I have to also upgrade the app just to get them again. Still a great app had it a long time just sad we couldnt keep what we had.
