The app is ridiculously slow when it comes to synching, moving from one step to another. Some stores don't carry the same inventory and I'm left replacing an item the site doesn't carry. The all will just lose ratings also. I went from about 50 to below 40 ratings & it in turn brought my 4.89 rating down as it lost most of the higher rratings I had. I am now down to 4.7 & missing batches and losing money because of the app, not my actual service.
