Facebook Messenger channel connects successfully to my Business Manager. Instagram connection consistently fails at business.facebook.com/business/loginpage/igoidc/callback with 'Sorry, something went wrong' — across Safari, Chrome, incognito, and the mobile app, with cross-site tracking disabled. This looks like the issue is isolated to the Instagram OIDC callback specifically, not general Facebook auth. I have been struggling for weeks with this.
