Upset – WhiteBoard or DrawingBoard Review

I purchased the app to get rid of the ads because one came up and started using cuss words ( I use this app with students in my classroom). It worked well last spring, but I went to use it today and the ads are back! I am not happy about it! I really want this fixed or my $10.99 refunded!!
