Dear @dlive and @mehdibca, just to let you know that apparently playing around with the Tags set by DLive in Busy or Steemit after publication seems to break the link between the post on the blockchain and the video.
I have the problem for this video
https://dlive.io/video/sorin.cristescu/4ea98525-aef8-11e8-91f1-0242ac110003
which was working fine before I thought I'd rearrange the tags from busy ...
Could yuo please maybe have a look and try to fix it ? I promise I won't touch the tags anymore ! :-)
