It works a few times – Whiteboard for kids: toddlers draw and color board Review

The app is AMAZING! 27 colors, preset shapes, undo/redo, erase all, and other things! But after a few times, it ranges to a white screen crashing an app or an ad popping up after about 3 seconds, crashing the app so I can’t use it. Please fix it and I’ll rate it 5 stars. Edit: I tried it on a phone and it worked 1 time.
