Hi :-)
First of all, the "Match Framerate" option in tvOS 11.2 is really cool!!!! :-)
But I see there is one little issue with it:
"Match Framerate" is enabled globally for ALL tvOS Apps...
But the problem is, there are some older Apps (which get no Update since a long time), so these Apps don't get optimized for this new Feature!!!
The result is => The "Switching" happens often, also if there is no need... We see often flickers from TV etc...
Apple should make a customziable List for choosing which Apps have this "Match Framerate"-Feature enabled but NOT globally enable this ;-)
