At what time and in what timezone does the limit reset? I'm trying to plan my day.

It appears to me that you're only vetting designs that go on the marketplace, as mine publish to my shop immediately. If this is the case, it would be nice to move the limit to the number of designs that can be put on the marketplace per day.

I bumped up against the limit because I learned a better ways to do the designs, fixed them accordingly, and re-uploaded them. The last time I bumped up to the limit was when porting the designs in my old partner account to the new-style partner account.
