I recently downloaded Pokemon Bank, excited to transfer old Pokemon from my other games to Alpha Sapphire. When I had gone to download it in the EShop, there were no problems with the download, but once it had finished, it should have shown on the home screen, but the application was nowhere to be seen. I was wondering whether it might be a bug or if it isn't there for a reason.
It should be in a gift box or in a folder. Try downloading it again, or go on it from Pokemon transporter(or whatever its called)
