When I open the app, it stays open but when I try to change color, size, or background color, the menu doesn't open. The arrow changes from up to down but nothing opens

This is one of the first apps that intrigued me three years ago. It was perfect for quick drawing ideas and doodles. When I realized that the latest update took away the ads, I was very excited. I should've known better, though, because now the app won't stay open for two seconds. I hope this isn't a ploy to hinder us "lite" users and force us to hand over some money for the paid version. I'm terribly disappointed.

This app is super fun and easy, but when I had just finished a picture that had taken me half an hour, and I was about to save it to my photos, I jostled the screen just the tiniest bit and my picture disappeared forever

I have used in past and it worked great. Now I cannot get it to clear finished photo after being saved...
