Collection account: cannot enable only the CardDAV resources
I have a collection account containing IMAP, CalDAV and CardDAV resources. I want to enable only one CardDAV resource using Edit → Accounts. In that window, I can put a tick afront the colleciton account and afront each sub-accounts.
It is not possible to enable only the CardDAV accounts: whenever I remove the selection from the mail account, the CardDAV resources are unselected. However, enabling only the IMAP account does work.
