Caldav server for IOS - calendar-data

Question

I am building a caldav server. It is already working with many other clients but not with IOS caldav client. Server is implemented with python and it is running on the top of Apache 2.

When reading my server logfile I can see that IOS client is making multiple PROPFIND,OPTIONS,PROPPATCH and REPORT requests. (My server does not support PROPPATCH). IOS can find the calendar and calendar is visible as a calendar list on iPad calendar app.

The problem is that iPad calendar does not show any events or vtodos and I can see on logs that clients REPORT request do not contain any "calendar-data" prop's. I don't know why client does not ask calendar-data at any REPORT requests?

(Sorry for bad formatting. I Made lot of work to format content properly, but it was difficult to format XML and result is far from good)

Here some access log lines:

First, you haven't posted your response header for the Report Request to understand the complete response. Second is that within a Report Response body you must specify the status as "Http/1.1 200 OK", not as 207. 207 must be specified in the response header.
