I tried to test Deferred Deep Link using the App ads helper, but "Deep link notification could not be sent due to some error" An error occurs.

Company validation submission always prompts "Failed to execute query"

We have a Plivo account and created a WhatsApp Business Account with an Australian phone number purchased from Plivo.
The corresponding Meta dashboard shows the number and did have the number as active, but as we went through the verification process to add a custom name, it was disconnected, and now shows as Offline at the Meta end (disconnected at the Plivo end).
How do we switch it back to online at the Meta end?

We are using the Instagram Insights API to pull in follower by country. We are noticing the response is returning different percentages than the the App is showing us for accounts?
Has anyone experienced this, Do we know any potential reasons for this?
Your help is appreciated

It is incredible that Meta just want to make things complicated. I want to delete a business profile, but they say that I can't do it, without erasing the system user and ads account.
I cannot erase the system user :B And I don't have any ad account. Just a expire card that also I cannot remove...
