Let's be patient with this and not give him a hard time. For those of you who haven't used Sync before, there was a major update a while back which caused strong emotions from many people and caused the developer to take a hiatus. Please be patient and kind and the result will be worth it!
It had to do with how the cards were presented and how the quick menu and swipe up/down worked. I preferred the previous way but the new way worked just fine. Just took an extra click to use it how I wanted.
It came down to changing how it looked / worked after everyone was already used to how it currently was. People get upset for no good reason sometimes and this was one of those times.
