We’ve built an RTMS app on one sub account successfully. Have been getting the required data etc. Tried replicating the same app on our test sub account and RTMS is not auto-starting.

Context:

- License: Zoom Developer Pack Credits Monthly Usage plan assigned to sub account
- Scopes: meeting:read:meeting\_audio / \_video / \_transcript / \_chat / \_screenshare, rtms:read:rtms\_started / rtms\_stopped / rtms\_interrupted
- Event subscriptions: RTMS started/stopped/interrupted in Meeting, plus meeting started/ended/participant joined/left
- Account setting “Share realtime meeting content with apps” enabled and locked; App added with auto-start = All, permissions = Always allow; host is in the RTMS enabled group and has the app in personal settings
- App uninstalled/reinstalled on the host account multiple times

`meeting.rtms_started` never fires. Manually starting RTMS returns `{"code":2310,"message":"Failed to perform RTMS app operation."}`
