Great app, just a little buggy

I love this app. Great interface, great performance, and I love how simple it is to use and get used to! The pro tools are awesome, but they seem a little buggy, mostly after updating the IOS device. I updated my iPad a few days ago, and I had purchased the pro tools awhile back, but then after I updated my iPad all of the pro tools were available and working except the additional layers, it now only allows the normal 3 layers. All-in-all, it is one of my favorite apps on my iPad and I highly recommend it to anybody who likes to draw.
