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

Access via "WhatsApp Manager" Account Tools -> Flows, "verify your company" is displayed and when I click on verify it opens a modal saying "Congratulations, your company has been verified by Meta" and a button with the option to close the modal and return to the same previous screen. Don't get out of this loop.

Hello,
I am a certified tech provider, and I can't download the certificate after the business name was validated. I receive the email asking me to do so, but when I arrive on the phone number page, and I click view certificate, I'm not able to access it (see screenshot, text: The certificate is not available for your business. Only the business solution provider who manages integration with the WhatsApp Business Platform will be able to download the certificate.).
Am I missing something ? As a result, I can't send messages nor receive messages with the onboarded WABA phone number...
Thank you, Lucas

Hello,
I met all requirements to become a tech provider, was granted the following permissions: whatsapp_business_management, whatsapp_business_messaging, but I still can't fully onboard clients. At the end of the WhatsApp embedded signup flow, I see that everything is validated and that I should be able to communicate on behalf on my client.
However, when I go WhatsApp phone numbers in my business manager, I can see that the waba linked to my business has "unavailable" phone number. It's said that I should download the certificate, but I can't download it, instead I have this message: The certificate is not available for your business. Only the business solution provider who manages integration with the WhatsApp Business Platform will be able to download the certificate.
I also see that I am unable to send message to this phone number on WhatsApp.
Am I missing something?
