I have a brand new LG Smart TV. I cannot find HBO in the LG App menus to be able to add it to my list. Then when I try to access via the LG Browser, it tells me that I am unable to run the content as the browser needs to be updated. Can somebody tell me how I can access HBO Go via my new Smart TV? I have the LG - 55" Class - LED - Nano 8 Series - 2160p - Smart - 4K UHD TV with HDR, Model 55SM8600PUA. Thank you
