Live dashboard tiles report theme

Hi all,

I am currently building a dashboard, which contains a combination of pinned visuals out of reports and some live visuals build on streaming datasets. I have created a json theme, which works fine on the pinned visuals, yet it does not work on the live visuals. 

Does anybody know why this could be happening? Or if perhaps custom styling is not (yet) supported for live visuals. 

Best regards,

Han
