all i want is just the basic functionalities while casting video like pause/forward/rewind, just that basic, under this version 1280 right now it does not support, this is not a new technology but this is the first TV I encountered that does not support these. my set-up box 5 years ago could support it well.
I know in the newer model you have fixed this issue, so this is a known issue, please just upgrade our TVs to the latest version firmware, thanks.
8-series are supposed to be high-end, end up like this.
I'm sorry, we are unable to speculate on the release of future updates. We'll announce publicly if this info becomes available.
