Using chrome / firefox on my laptop the MY LG tab is at the far right on the tooldbar under the "..." symbol. Hovering over that link does nothing, clicking it only brings up my player card. No way to access API that I found. Using Internet Explorer Edge the MY LG button appears as depicted on the video and Api is easily accessible. Thanks. @LG_MCDONALD
I use safari on my MacBook. If I do not have the screen maximized then I have the same issue and clicking on it only bring up my player card.....When I do maximize my screen and hover over My LG it works fine and I can use the API. So in case anyone has any issues on Safari, just maximize your screen fully and it should work fine.
