[OBSOLETE] Hue (Re)Connect - with scene handling

I seem to be having a strange issue with linking my Hue bridge with this app. I have all five device handlers installed and published as well as the latest SmartApp but no matter what I get an Upgrade Needed error when I try to install this SmartApp. both my Hue bridge and my SmartThings hub are up to date. I can add my bridge and control my individual lights just fine with the stock Hue Connect SmartApp. I was having this issue previously as were many others in the thread linked below but ST pushed a code change and fixed that issue a few weeks back.
