The App Does Work on So Many Levels

I am having the worst time with this app. I feel like the winds and stars must align for this to work. No matter what gets done, there are constant error messages. Nothing and I mean nothing ever lists to ebay. Which is what it is used for so I thought. I am in bad loops where it says its not connected to ebay however we have fetched the key many times. It never takes. Its as if its never connected even when you verified its connection. Its horrible. And, I am in a typical case where what do they say about trying to do the same thing over and over and getting the same result? Thats where I am at now.
