I'm attempting to upload a video file using the "Record/Upload Media" tool in the RCE toolbar, but I am receiving this notification:

I turned on the new RCE Enhancements and the issue still persisted.

However, I'm able to add the .mov as a file using the "File Upload" feature on the right hand side, but not from the RCE "Record/Upload Media" tool. 

Can anyone please tell me how to resolve the issue?
