I'm now responsible for RLS and Admin stuff, there are internal reports, and some reports get shared with external users, my boss been using App to deliver Audience (one internal and then per report), so currently I'm keeping it as is.
so I went and created Security group for internal and one for each report, and Changed Audience and RLS for all report to use those groups instead of emails, and went and removed all RLS and Permissions (that was kept as read from the app).
Right now, I think using the App is okay since there's only 5 or so external reports, that's less than the 25 limit.
I like App to have one place to deliver everything, but given that there isn't much overlap and sometimes a report only have one external users, I don't really think this is the best thing, and I don't like the Horizontal Bar (Looks fine for end users, but as admin it is gonna be more annoying)
I think Sharing Links, or better yet, just giving them "Shared with me" URL is better, and internals can have the App since each Audience will have several reports.
I'm assuming if I click manage permission and add their Sec Group there it will be available in the shared with me
What do you think?
