To be clear, I'm talking about the workshop for my own game, and not clickteam's workshop.
I can get a submission to upload once, but I think due to the new/modifying distinction, it doesn't work after that. When testing to see if the user has already submitted something with the same title and then using "modify existing user submission" I get the following error: statusErrorFailedToShareCloudFile
If I try to just submit new again, it doesn't work. There's no example file for modifying existing submissions, so I'm not sure what to do here.
