Hi all, Is there a chance I could update my really old (2014) lgtv to latest (or at least later) os version? It was fine up until recently where newset hbo go app is not working with it (and older app is asking for update). Also it would be great to finally see twitch app in my store (as i know later os versions have it). Also, do you recommend update at all? Info: Software version: 05.05.70 webOS version: 1.4.0-2532 model: 47LB671V-ZB Country: Serbia Please let me know if you need any additional info and thanks in advance!
