We've seen a couple situations where users add mosaic widgets to their group Overview page and then the page "locks up." After the widget is added and the page is published, the group admins are unable to access the Manage button again. The only resolution we've found is copying the overview page to a new group and starting over. Any idea why this happens and how to fix it? Also, is there a max to the number of mosaic widgets that can be added to a group overview page?
