I've been having this bug for awhile now. Whenever I try to publish a model or place, I get the message ''Failed to upload, please try again''. I've tried re-installing numerous times.
Hello AfraidAnna,
This can occur at random times. Just publish it again...
1.Save the project.
2.Restart Studio
2A.[Log out first before restarting if possible]
3.Log back in.
4.Open the file
5.Try again.
