Hi @casey-chow ,
Thanks for your reply. Please see the attachments.
For existing version, the oauth is locked on “Predefined”.
If I updated the server version, the oauth now automatically switch to CIMD
It is automatically selected and editing is disabled. I expected the preselection should be the same as existing version. Hope that helps!
Thanks,
