Just uploaded my first gig, but have had trouble with uploading gig audio in mp3 format. I followed all the guidelines, kept the length and size within limits, but whenever I uploaded a file it rejected it with “This file type is not supported. Please try one of the following: MP3” . I have tried this with CBR and VBR mp3 files, have tried changing the case in the filetype in case that was the problem and tried uploading from two different browsers (Firefox and Edge, running on Windows 10).
Could you please advise on what I might be doing wrong here, or if anyone else has had this problem.
