BI Viewer component and OneStream 9.0.0

Hi all,

We upgraded one of our OS instances to 9.0.0

After a first look, it seems BI Viewer does not work anymore from Desktop app, but charts are showing from Modern Browser interface, any idea? Can't find a clue on Know Issues.

On Desktop app, only the layout shows, no content:

Same Dashboard from Modern Experience shows fine (I blurred data here)

Any advice?
