After iphone and ipad updated to iOS 11.3.1, Safari has problem of downloading and opening .ics file to add event to Calendar. 'Add to calendar' page unexpected quit in a second.
If I remove a url from an existing page and paste the link which with download .ics file, all work fine and I am able to add event to calendar, but if open a new blank tab and paste the link, the page will quit unexpectedly.
I tried many devices which using iSO11.3.1 include iphone 7+, iphone8, ipad mini4, same problem occured.
Do you have any idea to solve this issue? Thanks in advance.
