Hi Team,
We are encountering an issue where a particular customer is unable to receive WhatsApp messages through the Cloud API. The error we received is "message undeliverable" with error code: 131026.
This problem appears to be specific to the Cloud API. When we send the same template to Android users and iOS devices, it gets delivered to Android but not to iOS devices. However, some messages are getting delivered to some iOS devices, while others are failing. The customer is valid, and there are no other issues.
Please provide any additional details or resolutions. This information will assist us in troubleshooting and identifying the underlying problem.
This issue is impacting our customer experience in the Production Environment.
Best regards, LucidPlus IT Solutions
Getting the same behavior. If I send a message from the recipient device to the business number, after that I am able to send the template message normally. But not able to send the same if the user does not have an open conversation with the business number.
