My problem: I use Google's CalDAV APIs to read and write on the Google calendar. It works fine on all calendars but the user's primary calendar. Reading works fine on the user's primary calendar (calendar id is the same as that user's email address), but when I try to write (with a PUT request) I get an HTTP error response with status 403 (need-privileges)
I use scope calendar, task an cardav;
Thanks for you help
