RAB Lightcloud Blue

this was a really cool app for smart lights at one point but now it just seems to be broken. it requires a login every time you close or even change apps. it won't connect to any of my lights now so basically I just have expensive light bulbs I can't control that are currently set to different color and dim levels. I really liked using these smart bulbs and thought the smart shift was a really cool feature. But it has been months now that the app isn't working so I assume this product was killed
