Failed to save credentials
See Connection troubleshooting for the full list. The first thing to check is that the WhatsApp Business Account ID field does not contain the Phone Number ID.
The red connection-expired banner
MsgOrb marks the connection expired when Meta rejects the stored token. Reconnect on WhatsApp Settings with a permanent System User token.
The amber expiring banner
The stored token has an expiry less than seven days away. Replace it with a permanent one before it lapses.
Number Health shows nothing
The card reads live from Meta. Empty values usually mean the credentials no longer work or point at the wrong WhatsApp Business Account.
Everything looks connected but templates will not submit
Template submission needs the WABA ID specifically. A connection that can send but cannot submit templates is the signature of a missing or wrong WhatsApp Business Account ID. Re-enter it in Advanced Setup → Manual WABA Configuration.
