I never accepted the LG_App_Store User Agreement when first opened after factory reset. It does not allow me to go further and be able to search/instal other apps, but my browser newer updated again- which I believe might have been the issue in the first place.
Now, I can continue to use the pause and play buttons on the remote for web streaming (previously disabled by the update) and no longer get the fireworks screen after 20 min.
Terrible sacrifice! Anyway got all my apps on either Apple TV, Google Chromestick or Amazon FireStick.
