On Safari, WIX Video player (single video player) works, but shows just a blank black canvas, instead of the normal canvas video image, before the video is played. It only happens on Safari. On Edge, FireFox, Chrome, on both Mac and PC and iPad, the video canvas image shows. The video is an .mp4 video file in DropBox.
Bugs and system issues should be reported to Wix Customer Care to ensure timely handling of your issues.
