on both my Mac and iPad the platform.appgyver.com doesn’t work properly (any more). All the header menu items (Launch, Theme, Navigation …) have no response when clicked.
Chrome still works.
Thank you for re-instating Safari, again. (Or, is it a wrong Safari configuration?)
We’re looking into the issue with that version of Safari and Composer, thanks for reporting about it. In the meanwhile I’d recommend using Chrome to work on your apps.
