If you’re getting the “No permissions available” error while assigning permissions to a system user in Meta Business Manager, it usually means the app isn’t properly connected to your Business Account or doesn’t yet have access to WhatsApp Business API assets.
To fix this issue:
Go to Business Settings → Accounts → Apps and ensure your app is added to the business.
In System Users, assign the app to your system user before trying to set permissions.
Make sure the app is at least 24 hours old (Meta restricts new apps).
Check that your WhatsApp Business Account and Phone Number are properly linked under the same business.
If it still doesn’t work, contact Meta Support via Developer Support → App Review after 24 hours.
