Why can't i screen mirror from my tv to phone?

AC Question

Recently I tried to screen mirror my Samsung Galaxy S6 edge+ to my Samsung TV. Everything used to work fine and now it doesn't work. The only thing I can do is use Smart View and this will only mirror my phone to TV but won't mirror my TV to phone. I can only assume that this happened because of the recent update. Does anyone have any suggestions or solutions before I have it out with a Samsung rep? Thanks.
