Hi,
after uploading a song with the Master Interface I can’t play the song. There is an Icon with the Tooltip “Transcode pending”. But even after an hour I can’t play the song. Even if I upload the same song, that worked before.
@larsalles There is a bit of a backlog of background tasks at the moment. Hopefully it will clear up soon. I will take a look as soon as I can about manually clearing the backlog.
It works now, thank you very much ! 
After uploading one song I now have multiple transcode pending, making preparing for my game very difficult.
@jamesinseattle We are testing a new search engine and the background tasks to keep the search index up to date are competing with the background tasks to transcode uploaded samples. We are investigating the bottleneck, and in the mean time I have reduced the frequency of search index updates. Hopefully that helps, and hopefully we will have some improvements to the search index update tasks soon as well.
