CalDAV does not work with macOS and iOS
 

Hello RB users,
I have been using RB service for about 3 months now. Email and contact sync (via CardDAV) works just great. However, from day one, Calendar sync with macOS and iOS devices has not worked at all, using CalDAV.

Any hints and help to get this working will be greatly appreciated.

On macOS and iOS, the account can be added as CalDAV, however, no sync of calendar invites, either sent or received, works.

Cannot comment on macOS and iOS devices, but have succesfully added calendars to Windows, Linux and Android.

Have you logged into:

https://dav.runbox.com/calendars

And then found any existing calendars, or added a new calendar and copied the URL to use on your device(s)?

Yes I have tried with no resolution. And now have a ticket open with RB as well. They are looking into it.

What do you use for Android CalDAV sync?

A couple of options are CalDAV-sync by dmfs. This stopped working for me and I couldn’t get it to work again. Another is Calendar Sync - I don’t see developer name on Play store but she has an email address at gmx.at and is very responsive. The interface is very different and it’s pricey at £7.99 but seems robust. There’s a trial version that lasts 2 weeks.
