Do you need to change a member's permissions level?
Navigate to menu -> Manage Account -> Members
The member list is shown.
Search for a member by email in the search bar.
To edit a member’s permissions, click the Pencil icon next to their name.
Then, select their new permission set.
You can only edit an existing member's permission level.
If the email was mis-typed on initial invite, delete the member and re-add the correct email.
