Gentleman, why app Happycast in combination with my ipad air 2 with ios 10 don' t work?  I have tried with 5 Ghz and only 2.4 Ghz connection wifi, ipad show me icon tv box but it not connect with tv box: message impossible to connect..why? There is a system to update app happycast to another version , now is 4.3.0 .. I select tv box, 1080 or 720, mirroring and no framerate.. Thank you to everybody
