I can't upload .mov files

I tried to upload a .mov clip with the new uploader tool but it doesn’t show up in the folder. I had to change the extension to .mp4 to work.

Problem also solved by changing to .mp4 Thank you for post. Same problem, again with new uploader, when loading to the web site. It took the file but at the end of the upload error messages said the following were not present:" file size not in bytes, duration Not in ms, Not either h264, mjpeg,prres, or png. Not resizable. Not 23.98 etc".
Note… 2018 Premier Pro Res 422HQ export defaults to mov.
