- OnlineMeetings API + Application Access Policy match users by OID;
UPN routing returns 404. Resolve UPN -> OID before all Graph calls.
- Transcript content endpoint rejects default Accept '*/*';
add ?$format=text/vtt + Accept header + responseType('text').
- aiInsights moved to /copilot/users/{oid}/onlineMeetings/{mid}/aiInsights (Beta).
List call returns metadata only; fetch detail per insight for
meetingNotes/actionItems/mentions.
