known issues

As of 2012-05-09 Yahoo's server seem completely broken! It's almost impossible to get a valid response from the servers above. The error codes vary from 401 and 404 to 502, 503, 504 or the connections just times out. Please note that this is not a bug in CardDAV-Sync or CalDAV-Sync. This is a server issue!

Update (2012-11-19): Currently this is more an issue with CardDAV than with CalDAV. In CalDAV-Sync you may not be able to add an account. Just retry later in that case. Also you may get an error notification from time to time (with an error code of 400 or something from 500 to 504). You can safely ignore that errors. The app retries 10 times to sync in case of an error, but sometimes event the 10th attempt results in an error. The next sync will probably work well.

In CardDAV-Sync the retry-approach doesn't work. For some users every attempt to sync returns an error code 500. Unfortunately it's impossible to sync in that case. Note that not only CardDAV-Sync is affected, OSX users see that issue too (see Error when try to sync Yahoo account with Contacts app and Mac address book sync with yahoo contacts does not work in OS X 10.8. ...).

Some users from France reported authentication problems. Please try the following URLs in that case:

CalDAV-Sync

caldav.calendar.yahoo.com/principals/users/

or

caldav.calendar.yahoo.com/principals/users/<your Yahoo! ID>/

CardDAV-Sync

carddav.address.yahoo.com/principals/users/

or

carddav.address.yahoo.com/principals/users/<your Yahoo! ID>/

Please let me know which one works for you!
