I don’t know if this is a Picard problem or an AcoustID problem. It has happened before, and at that time it was an AcoustID problem. When using Picard to submit fingerprints to a MusicBrainz release (via AcoustID) I hit the Submit AcoustIDs button and Picard reports “AcoustID submission finished successfully”, but when I inspect the Recordings on MusicBrainz afterwards it reports that the recordings do not have any Fingerprints associated to them. Can anybody say whether or not AcoustID/MusicBrainz is aware of this, and if so, if anything is being done about it?
