For me, the app works without hesitation and I can control it all and set in terms of lamps per se, but I can not log in myhue and thus do not share any scenes or download other and thus also the positioning service does not use the lights on and off automatically to turn my house if I am closer, or remove from it. Hope I'm not alone with the problem and it is a common mistake which is fixed soon. Also I'd appreciate apps such as Hue Disco! Otherwise, the app does what it is intended, does not crash, has a very comprehensible, and many updates hope :)
