I've put this in the official EA forums, but I know my track record in there for getting decent replies isn't great, so I'm going to post here too in the hopes that I get some sensible answers.
There have been numerous times where I've uploaded a lot or Sim or just recently, a world, to the Exchange via the launcher. The launcher says that it's been successfully uploaded, but it won't show up in my studio. I've tried deleting the item from my launcher and re-uploading it, but nothing.
I'm wondering why this happens, and more importantly, how to prevent it happening and ensure that they always appear in my studio.
Note: I don't use cc or mods
Any help on this matter would be greatly appreciated.
Below is a screenshot of what I'm talking about.
