You cannot view a query someone is editing. You receive the message "This resource is locked because it is currently being edited by [person's name]."
When someone is working on a query and asks for a second opinion or help doing something, you cannot view it until they save and leave the query. Otherwise you have to discuss without being able to see it or have a screen share call. It slows progress and turns a quick message back and forth into a larger time commitment.
I would prefer that you could view, edit, but not be able to save or at least view when someone else is editing a query.
When setting up new queries and dashboards this is a common issue. When we distribute queries for stakeholders to review and suggest their changes, we cannot make changes in real time unless we're in a screen sharing call.
