I created a calendar web part on a site page in SharePoint online using IE. One of the users has a Mac, and uses Safari on it. Now this calendar loads as empty with no events every time he accesses the page, it also does nothing when trying to navigate to the next month. If I use safari on windows I get the same issue as well. Oddly if I click "Edit Page", the calendar events load. So it is clearly capable, but just refuses to do so. I've researched into this and found various issues with Safari and SharePoint, but not this particular one.
Any thoughts on this one?
