Update. I managed to get it work by adding only 1 tag to the post.
If I have more than 1 tag I get error message that post cannot be made to the blockchain.
Here is the link to the video.
I wanted you to see me singing, but of course, I can not post the video on DTube.
But you can always see me here :D For my luck.
It was The Cranberries - Zombie :D
You can easily imagine how it sounds like :D
