Recently I created an account on MusicBrainz and I imported my scrobbles from Last.fm to ListenBrainz. Operation was successful and everything went OK. Then several times in the last days I repeated the operation and added a scrobble manually - every time without problems - number scrobbles from Last.fm equals with ListenBrainz.
Last Wednesday, there was a problem. Scrobbles have been added but their number from Last.fm does not match with ListenBrainz - some of them have been duplicated. For example, Last.fm has 78,351 and ListenBrainz 78,508.
Several times I tried to reset import timestamp but no effect - the problem still occurs.
Is there any way to remove all listens from ListenBrainz and import them again? Because apparently, mirror synchronization does not work.
P.S. I have to add that I have never been a user of ListenBrainz Alpha.
