MLB Games on Airplay no longer working

I used to be able to transmit my MLB games from my iphone5 to my TV. Once I upgraded to IOS 9.3.2 that stopped working (I do not remember what ios I has previously). What can I do? I'd love to revert somehow back to ios 8 something just to try to get it back or does someone have any suggestions or know about MLB issue?

Thanks!
