Hi, I'm trying to make playble ads for facebook, now I first decided to upload it for testing on developers.facebook.com/tools/playable-preview and got a black screen, I know there is already a topic on the forum about this but the last post in it was made 3 years ago, has this problem been solved now ? I tried to make a test project consisting solely of text and call to action facebook script, but still only see a black screen
