I've noticed the problem of controlling / casting to a my Samsung TV from iOS devices (app v4.7, iPhone 5 and 6s) no longer works as of a few weeks ago. My TV no longer shows as a Player to select from.
I can select the player and cast to/from my PMS to the Samsung TV and my iOS devices, but iOS app no longer identifies my Samsung TV.
Is anyone else experiencing this issue and are there any ideas on how to fix it? The functionality used to work great (before iOS app v4.7).
