I asked the same question before, but it still does not work,
so I ask again hoping someone can help.
I did create new fiori launchpad site like followings. (I'm using trial account)
In site diretory > create site > add some site name and select SAP Fiori Launchpad, then create. > new window opens with waring image where I can't do anyting .
I added TENANT_ADMIN role to my user.
Also, Principal Propagation is enabled.
What else do I missed?
By the way, I didn't have this kind of trouble last month.
