I got so fed up with my LG TV lacking streaming I went and bought an Amazon Firestick and put in one one of the HDMI slots at the back of the TV - now I have no problems streaming. LG TV technology is poor.
There are a lot of YouTube videos as well that help you to set it up your FireStick. There is one called Tanya Firestick where she even has a live chat every Wednesday to answer questions live.
