I have a similar problem with Ubuntu 17.10. After pasting my ICS URL (from Zimbra), the Add button stays grayed out. If I use the read-only URL (offered by Zimbra, with an .html at the end) it adds the calendar but no event is shown. And when clinking at the calendar it opens it at my browser. Besides this it keeps crashing without warning in some random situations.
