Mate 20 Pro issue.
I started using the the phone for a variety of video capture purposes. Regardless of the source, I cannot upload the full resolution videos to YouTube. The screen recorder feature utilizes a native 720p(50fps?) but YouTube will only finalize said videos at 480p50. I shot a short 4k video days ago and it's only showing up at 480p as well. Yesterday I shot a 1080p 60fps video and YouTube only uploaded it as 48060 as well.
I'm not sure why this is happening or how to fix it, but it's only happening on this device. I have an old Galaxy S7 and videos are uploaded fine on that. My friends and family aren't having issues either. What can I do?
