For clients in industries that deal with personal information — tax, healthcare, finance, legal — that all-or-nothing setup makes them uncomfortable, and honestly it should.
What we need is a "Grant Support Access" button inside each subaccount. The client flips it on when they need help, we get in, fix the issue, and they flip it off. Same control HighLevel gives us, passed down to the people actually trusting us with their data.
It would make clients feel safer, make support faster, and build real trust — especially for those of us selling into regulated industries.
