Hi ShiroEd,
Did you ever manage to get the Freeview Play working?
I have had a LG OLED65C6V for about a month, great TV, but freeview play doesn't work. I have had several OS level updates since purchase. All apps relevant to catch up are installed and up to date but the guide scrolling back function just seems broken. When watching a major channel (BBC, ITV or C4) I can bring up the guide to show what is currently on or upcoming but on scrolling back all the same channels (and others) with catch up function (alleged) disappear leaving only channels like Pick, etc. in their place. It's like some kind of weird bug. As you state the Freeview Play logo is present and the internet works fine on the TV, e.g. I can get 4K Grand Tour on Amazon without issue.
I feel that either the software function isn't there yet or that I need to change a setting somewhere that I haven't found yet (I had a similar issue with 4K HDR Blu Ray not working until I got the standard settings corrected!).
So have you succeeded, did you ever get Freeview Play working? If you did how did you do it?
Thanks
