Plex Cloud Beta Setup Issue

Hi, I have just tried to setup the Plex Cloud Beta but seem to be stumbling at the first hurdle. I have selected OneDrive as my cloud storage provider but after granting permission, I simply get the message “Plex Cloud Setup
An error occurred creating your Plex Cloud server.”

No other options from here. Can anyone advise?

You’d probably be better off posting your question in the Plex Cloud Beta forum.
