CalDav calendar not working on iphone 5 with IOS 9.1
Does somebody know a solution for my problem of my iphone 5 with IOS 9.1 not synchronizing my calendar on my synology CalDav server?
I am using these facilities on my synology server: https://www.synology.com/en-global/knowledgebase/tutorials/463
The weird thing is that this all works on my ipad with IOS 9.1, but not on my iphone 5
I have exactly the same settings on my iphone as on my ipad.
The ipad works flawlessly together with Android smartphones of my family and with MS-Outlook.
But the iphone doesn't.
The connected calendars show up as an calendar/agenda in the Calendar app, but without any content.
iPhone 5, iOS 9.1
