I've enabled Client Report Access for one client and customized the appearance with their logo. Now I want to enable it for another client but it seems I can only customize it once.
Maybe this doesn't cover the concept but I would like to customize Client Report Access pages different for each client. I guess this is not possible (yet)?
You're right, it's not possible. The client report access page is per account not per client, so the URL and any display customizations will be the same for all clients.
