Is Reach file share shut down now?

Doesn’t let me upload anymore, but still lets me delete stuff. Tonight I tried to upload a couple of Firefight game types to my file share (my first upload in over 5 years) and it just tells me “name of creator of this file is not allowed on Xbox Live”. That isn’t true because I can clearly play on XBL and definitely not banned on any game. Plus, my GT is well over 10 years old and never changed. Does it give this message to everyone now when trying to upload to Reach’s file share? If so, what year did they decide to do this? This kind of kills Forge and Customs in a way. Does it only do this on Xbox One?

Had no problems a couple of days ago, on Xbox 360.
