I can't post on dtube either. My video and snap appear to both upload but when I click submit, I get an error message that says please upload a video before submitting. I have searched and searched for an answer. The only suggestions I get are be patient, try in a couple hours, use YouTube then embed that in your Steemit post. Why can't I just use dtube? Are they working on fixing this?
I keep seeing posts about how dtube is better than YouTube. No it's not, at least not until I can actually use it. I know my reply doesn't help you, but you're not alone, I feel your frustration.

I blogged about this myself. Please let me know if you find a solution. Good luck.
