Yes, but this didn't work.
I am beginning to think the issue is because it is picking up my current on prem installation as I am able to see the RADIUS server under the on prem console.
I advised support that I would need to run the two systems side by side and was told this was possible, however I am now thinking it is not.
I also think there is an issue with the way it has pulled the license from my business account as I am now unable to issue invites.
