Hello,
How long does it take to get an answer or some kind of feedback after a submission to the asset store?
I submitted on August 29th. And on the Asset Store Publisher page under the Pending tab it shows the status is uploaded:
Package Size Status Updated
AC Clips Vol. 1 0 KB Uploaded 2014-08-29
The one thing I am worried about is it shows that the size is 0 and I uploaded 49 audio files. Is there a reason for that?
The 29th was Friday. My common sense is tingling, indicating they might just have too much work to get through to finish by the weekend 
4-6 days. If it takes longer email Caitlyn.
Your package is not submitted, it is just uploaded.
Status for submitted package should be “Pending Review”, try to reupload it.
If it won’t go into “Pending Review”, make sure you’ve entered some text in the Release Notes field. It’s required, even if this is the first version.
