Should I continue to put up 1080p and 4k versions of vids? Since I'm a newbie, I didn't know if there was going to be a difference!  I'd like to know what your experience is, as I want you all to have the best experience! On MV, some people have struggled to play anything above 1080P and on their phones. Please let me know!
