360 Video Media Texture Not Playing after Packaging

I have a 360 Video Media Texture wrapped on a SkySphere that works fine in the editor, but when I package the game the video doesn’t play after starting the game. I have a normal video in the level that works fine. I’ve made sure the media player url is a relative path and I’ve triggered it to automatically play in the level blueprint. Is anyone else having problems getting 360 videos to work in the build?
