We have Implemented onboarding for WhatsApp Business App users following the Customizing the default flow docs. Unfortunately unable to complete the onboarding as I am facing issues with number verification and unable to proceed further. Tried with multiple numbers from supported countries(Thailand, Brazil and UAE)

I'm using SDK to log in with facebook, but I'm getting a screen that says I need “support permission”. What could it be?

Hi, After implementing the data deletion request callback as you provide here https://developers.facebook.com/docs/development/create-an-app/app-dashboard/data-deletion-callback It results that is not working. After debugging the call, it shows that the first part from $_POST['signed_request'] splitted here:
`code' list($encoded_sig, $payload) = explode('.', $signed_request, 2); `
$encoded_sig is a 23 char string that implies not to be a valid base64 string. Even after adding "=" at the end, still not a valid base64 string. Note that we are also replacing the "-_" characters as you state in the code provided in the previous page.
` return base64_decode(strtr($input, '-_', '+/')); `
But always, after decoding $encoded_sig, it results in a broken string with broken characters like "\s�������\׉����~.4b���c�� ��". Could you help us to figure out what are you returning to us? BR.
