I have recently been unable to play any Amazon Prime videos on my LG OLED 4k tv which is about 1 year old. If I use the Prime button on the remote and select a video, it will say 'something went wrong - try again later'. If I use the Web OS browser and go to the Amazon site, when I select a video I get a message that says I need to update my Google Chrome browser in order to play videos. I checked for any updates but it said none were available. How do I update the browser on the LG tv? Also, I have no issue playing Amazon Prime videos on my laptop computer so it's not an internet problem. Thanks in advance.
