I manually added around 10 SMS messages to an existing campaign.
In the campaign's sending history, the status is inconsistent:
For some contacts, it correctly shows "SMS sent".
For others, it only shows "Added to campaign", with the next step being Message #2 — Email, scheduled to be sent in 3 days.
This makes it look as though the SMS is still pending and has not actually been sent.
However, the SMS has been sent successfully. When checking the actual sending activity, the tool was triggered and the SMS was successfully sent through GatewayAPI.
What's strange is that the SMS sending itself works correctly, but the "SMS sent" status is sometimes missing from the campaign's sending history.
Steps to Reproduce
Manually add SMS messages to a campaign.
Open the sent message (campaing) in the interface.
Check whether the SMS step is displayed in the campaign flow.
Compare it with the data available in GatewayAPI to confirm that the SMS messages were actually sent.
Observed result: The SMS step may be missing from the campaign interface even though the corresponding SMS messages are present in GatewayAPI.
Expected behavior
Whenever a manually added SMS has been successfully sent through GatewayAPI, the campaign history and statistics should reflect this and show the SMS as sent, rather than leaving it as "Added to campaign" or "Pending".
