Share a session plan with your client

Open the plan and share it.

If the client has no email on file the app tells you: "No email address on file for this client. Send them the link yourself."

Once shared, the client can approve the plan. If you change it after they have approved, they approve again, and the screen says so: make the change, then they can approve it. That is deliberate, so an approval always refers to the version they actually read.
