Q: Apple tv4 airplay buffers fine but does not play/start

i just upgraded my apple tv4 to ios 9.2. After upgrade, airplay from my iphone 6s plus (ios 9.3) is not working. When i airplay any clip from safari onto my apple tv, i see the clip is buffering fine on tv but it just does not start despite i hit play on remote and on iphone !!!!! .. some clips are 10-30 mins long. They get buffered completely but apple tv wont play/start them despite i hit play on remote ???

i have factory restored apple tv thinking that might be issue but still same.
