Amazon Digital Signage Stick portrait support coming?

In the closed topic from a few months ago, there was indication that more integration was coming and then with RDM being released we didn’t get any rotation support that I can tell.

Even in the inital announcement about signage stick support on this page:

It shows only vertical content in the pictures.

Any update? Thanks for all that has been done, so far. This would make a half-solution into a full one for us.
