Can't Get Native Video Player to Open

I’m not sure if I’m missing something, but I can’t get the native video player to open when using the ‘Open Video Player’ logic connected to a ‘Component Tap Event.’ The target YouTube URL is formatted using the proper instructions covered under a number of forum posts, yet I can’t get the native player itself to open at all.

I’ve tried using both the iOS preview app and the AppGyver web app, and both with no luck.

Any help would be truly appreciated!
