Since today i can access the CMS button in the designer, only once.
If i click the button, the CMS-collections appear and i can edit.
After doing a edit in a collection, i close the menu.
If i want to open the CMS-menu again by clicking on the CMS icon in the designer, i can see and outline of an active menu item, but the menu does not show.
I’m on Win10 Latest version and Chrome Latest version (71.0.3578.80)
Only solution is completly reloading the page, so i can edit a CMS item once, then save, then reload the browser/page again if i want edit another.
This is what i see after editing a collection item, closing it, and then trying to open again:
