Xbox One X 4k screenshot uploads not working

Picked up an Xbox One X to play the various remasters at 4k/HDR.

And I cannot upload screenshots to OneDrive.

Take the pic, go to Captures>Upload>OneDrive and get a sad face “Something went wrong. Sorry, something went wrong when uploading this clip to OneDrive”.

Anyone else see this? I’m Downloading Upload Studio to see if that helps, we’ll see.
