IDE error - unable to add simulated dimmer switch - access denied

I’m trying to add a new simulated dimmer switch. I am using an unused network ID, etc, but getting this:
“Access Denied. We’re sorry, but you are not authorized to perform the requested operation.”

I am able to edit existing devices, and have added devices before successfully.
Logged in and out, tried to add a different device type, and so on, nothing is accepted.
The Smarthings status page shows no current outages.

Is there anything I can do to fix this, or should I raise a support call?
Thanks for any ideas.

I’m having the same issue right now. I had the issue earlier but I was logging into the wrong thing, but today I’m for sure logging into

Thanks for confirming the issue. It started working the next day for me as well.
