OAuth application rejected, but testing myself - works fine.

Hello,

I submitted an OAuth app for review, got rejected because reviewer hit OAuth app with client id [clientID] doesn't exist error. I triple-checked the ClientID, they match. For review, the app is set Public (but not listed in community).

I tested it myself (same environment) before and after submitting for review, it works just fine, meaning that the difference is in the fact that I'm in the Figma team that owns the app, but your reviewer is not.
The OAuth flow works correctly for the app owner, but external users cannot authenticate until the app is approved.

I’ve submitted a request for assistance, but getting ignored. Looking for help.
