I tried my best but I can not get anything to play, I suppose it is a live stream with no post stream option. I need to look into Vimm though because people rate it a great deal.
I hate posts with no comments, it is so demoralising and everyone deserves a comment - but we can all add value to pull in comments too - even with these app built posts you can post edit - add in a description about what the video is about and maybe a few still shot's to give people the idea - you can do this after the app posts at leisure or pre-create the post using your favourite front end and then copy paste it when the app post is on the blockchain using the edit function.
