Thanks a lot for the report. The fact that the sound is missing from your profile should be an issue and will look at it.

In the future I would suggest to use our Discord server to report this kind of issues, so that we can have it all in one spot easier to manage.

Relating to the song not playing, it is the nature of the IPFS network. If a file is not requested that often, then the caches will clean it up and it will naturally vanish from the cloud.

What you can do is go to upload and re-upload the music file (must be exactly the same file), then cancel and do not publish. That will refresh that file on IPFS network for some extra period of time... Or now you can republish your content again and monetize it again if you prefer... :)
