Instagram professional messaging is issued to a Page + Instagram pair. If that pair is missing, creatorDM cannot finish Meta login.
On your phone
- Open the Instagram app and go to your profile.
- Tap Edit profile.
- Under Public business information, tap Page.
- Choose:
- Connect existing Page if you already admin one
- Create Facebook Page if you do not
- Tap Done.
You should now see the Page name on Edit profile.
Then reconnect creatorDM
Return to Home → Connect Instagram and complete Meta login with the Facebook user that admins that Page. Use Edit settings so the new Page is checked.
If the Page connects in Instagram but still does not show in creatorDM, follow Instagram account not listed.
