On slower internet setups the beat uploads timeout and abort the entire process in the new Beatstars studio Tracks section when attempting to upload a new track or update an existing one. When a faster service/area isn't available the only workaround has been switching back to the old tracks section and uploading it there. The track uploads work great on faster internets services but I ran into the issue multiple times when I was working in a slower location, whereas on the old track section it would take forever to upload but would not timeout and would allow it to complete. I believe the issue occurred on a service with a 25mb upload speed limit
Thank you for reporting your issue. We are working on a new version of track uploads, which will help with the workflow. More news to come soon!
