@YouTube I am trying to upload a video onto YouTube and it is saying it is not a supported field type even though I am using a supported field type MP4. Please help have uploaded videos before and never have had this happen to me.
Thanks for the info. Could you try clearing your browser's cache/cookies to see if that makes a difference? Also, try uploading it on Incognito mode or on a different browser? Let us it it fixes the issue.
