Good but bad

My 4 and 1/2 yr old loves this app but it is constantly buggy. Freezes, works weird, stops working. Was instructed to uninstall and reinstall to fix glitches and I have completely lost my $20 purchase! It expects me to pay for it again! Sadly customer service takes forever to get back so I can only imagine how long it will take to resolve this.
