Just hit the limit on uploading to the free 100mb of storage a few minutes ago. Deleted a ton of stuff, the amount I have shouldn't be more than 70mb, but my account is still showing 100/100 and it definitely won't let me upload anything else right now. Do I need to wait awhile for deleted assets to "disappear" from my storage allowance? Upgrading is simply not an option for me at this time.
