MCP details save failed: Registration method cannot be changed after OAuth setup is complete

Hi team,

We’re preparing a new version submission and is currently blocked with the error "MCP details save failed: Registration method cannot be changed after OAuth setup is complete." . Would love to get clarification on this.

We version our mcp server with route path and our current live app use this /api/v1/chatgpt-app/0.0.1 server. It was oauth with DCR and is shown as “Predefined” at the moment.

Now we want to submit another version 1.1.0 which use the server on /api/v1/chatgpt-app/1.1.0. We make some update to our oauth which now support CIMD. When we prepare submission, the oauth automatically resolve and lock to “CIMD”.

I believe the error “MCP details save failed: Registration method cannot be changed after OAuth setup is complete.” is related to oauth changed to “CIMD”; but that field is not editable.

Could you assist with this issue please? Thanks!
