Hi, I have just got my new LG 49LJ594V TV hung on the wall and so far I love it but I have a few questions. Can it be linked to Alexa? Can I upgrade the webOS past 3.7? Currently it says that it is running software 04.70.50 and no further updates are available and the webOS version is 3.7.2-57413 (dreadlocks2-drto) Any advise will be greatly recieved Paul
