Sharing a Workspace, PBI report or App with external users

Previously, i.e. January/February 2023, the external users when logged into their PBI account through app.powerbi.com saw a tab "from external organisations" next to "Recent", "Favorites" and "My Apps".

Now this is not the case.

I have got 3 external users who are registered as "guest" users in my tenant. They have PBI Pro licences.

How can I make the Direct Access work? What is the secret setting somewhere in the MS universe that allows for it?

They can see the report when I share the link, but I would like them to be able to use the workspaces and apps I created. There are several report within each workspace, so it's more practical then have links.

Thank you.

P.S. I assigned them as Members to each of the workspaces for example. The other attempt was to give the direct access each report. But with no success.
