This is a 2012 LG TV so aware full functionality of the smart functions/apps will be limited however currently unable to get the LG Smart Store.
Youtube, Netflix and LG Smart store icons briefly appear in the apps list but then automatically disappear after doing 'Initialisation of Premium' via the standard menu, I'm guessing this is due to the Country/Area group its set to is wrong for the UK.
Unable to change the country group, Area option can be changed which alters the country group but none make any difference. So believe its the country group that needs changing....
