Incorrect info I bought the app and now see all kinds of misinfo. For example in the lesson on squaring numbers 20 through 29. The steps are incorrect. Also it states that 6^2 + 26 is 64. 36 plus 26 is 62. I really like the app but just cannot reconcile the incorrect info with the fact that I spent over 2 dollars on this. Please refund this or dix the app. Honestly I don't want a refund but rather correct info. Thanks.
I want to get my money refunded It's not worth the money because of lots of errors in the app eg. Square between 20-29. Kindly suggest how can I apply for refund.
