Certain Screen resolution hides main navigation but doesn't show minimal navigation
When displaying a collective and using an older Ipad the main navigation is not visible - you can only edit the main settings of the collective.
Reason is that in certain resolutions the main navigation bar is hidden, but the minimal navigation to change the page is not yet displayed. You can reproduce it by displaying a collective in a larger browser window. When you then reduce the horizontal size of the window gradually you will see that first the main navigation is hidden an for a certain amount of pixel only the hamburger menu is displayed. Only after a few more pixels later the smaller navigation menu is displayed.
