Hi, I am having a (frustrating) problem with Amazon Prime app in my Oled 65EF950V TV: The subtitles have very limited options for customization. More specifically, even in the biggest font option, they are very small. It's not that I can't read them, but they are ridiculously concentrated in a small portion of the screen that they distract the viewer from the action. Normally I'd prefer the outlined font and not background, and this is not possible. Also, some of the subtitles are terribly out of sync. And I cannot see any option to change that. I am very pleased with Netflix subtitles, just to use an example. Is there any workaround for fixing any of the above? Thanks!
