It appears that only super admins can view the dashboard on multi-site installations. Is there an option/hook to allow for site admins to also view the dashboard
Yeah Query Monitor uses the view_query_monitor meta capability which maps to manage_options on a single site installation.
On a Multisite installation it doesn’t map to anything, which means only Super Admins can view QM because by default they can do anything regardless of capabilities.
You can grant the view_query_monitor capability to a user role or individual user and they’ll be able to use it.
