Hi,
Are you using the latest plugin version?
We normally fixed that issue in the “Plugins” page where our add-ons were checking about licenses’ statuses on each page loads.
We did not change that behavior in the update page, since admins should actually expect all plugins installed on the site to check for updates while browsing this page.
That said, I agree that it affects the loading speed of that page. Not sure I see a solution actually, except probably adding an “update” button, but that would prevent “automatic updates”.
Regards.
