I find the app works quite well and use it all the time, no issues. Please remember it is an app, designed for use on a small screen so of course it can't do everything that can be achieved on the full site. I believe that half the issues people have with the app is that they never bother to install updates. I do all my purchasing on the app and find it an invaluable tool for selling. I would not use anything but the full site for loading and editing pictures and it doesn't handle invoicing but apart from that it's great.
