A: Hello!

If you have HUGE video files (over 400mb), you're better off uploading directly to YouTube and sharing that YouTube URL across your other socials if you're in a hurry. Try to create optimized video files if possible and it will go much faster and smoother. Each network takes time to process videos and they can get queued. We don't verify them as sent until the social network sends our API the response that it was actually posted.
