Haha, no answer for you there I'm afraid, I'm impressed with 26 seconds.
I may be able to help you though with your video, not appearing in your feed.
When you upload via dtube, pull down the menu in the top right. You'll see a red dtube bar and a blue steem bar (both with pull down arrows). Make sure that you are signed into both, dtube and steem 😎
Peace.
