All services available. This coming Saturday the 19th of April, at 10:00 CEST, we'll be doing scheduled maintenance to help up prepare our servers for our next major update. We expect the work to take around about 2 hours and do apologize for the inconvenience. During the scheduled maintenance, all of Wunderlist's services will be temporarily unavailable. This means that it won't be possible to log in, sync changes across devices, share lists etc.
