Hi. I have a 2019 samsung smart tv. As they removed the Smart IPTV, i have loaded it by USB stick. Its loaded fine and ive had my MAC activated. I get the full list of channels, but none of them load. Its says its loading ,but then says stream error. Is it because its a "tizen" tv or some other reason it is not working. Hope someone can give me some advise. Thanks in advance. Gary.
