Hello,
I have one Sony Bravia KD-43XF7096 and my external playlist doesn't refresh properly.
I have removed long time ago some channels and added anothers but the list still with the same since the first time that I added it.
Already removed the list from the playlist, turned off the tv, waited few minutes to add it again and the list still the same.
On a LG tv works without any issue, updates perfectly
