I'm about ready to throw in the towel.
I bought Sketchbook Pro for Ipad around four years ago for 10 USD and recently had to restore my ipad to try to get it back to ios7. Not only did that not work but I can no longer download sketchbook pro from the store, locking me out of my drawings. I go through the link to the store on Autodesk's home page for Sketchbook Pro and all it tells me is that it is not avaliable in the US store.
I'm currently running Ipad2 ios8 wifi and my itunes is also up to date.
I'd like to have the problem fixed by Friday so I can submit my drawings to my college entrance portfolios (assuming sketchbook pro saved them, but I doubt it with my luck so far.) Honestly I'm really close to demanding my money back and buying a tablet for my computer and selling my ipad since drawing was the only thing I used it for.
Aplogies for my rant and bluntness, but this is a situation I'd rather avoid in the future.
I have noticed that some of the base Sketchbook products are now 'free'.

I would add a note in ther forum post here as they are more skilled in that 'area' via the AppStore.
