Thanks ebola … trying to configure & test, but getting the following error:

```auto
[2022-05-04 15:48:05] mautic.CRITICAL: Uncaught PHP Exception Symfony\Component\Debug\Exception\FatalThrowableError: "Attempted to load class "Api" from namespace "FacebookAds". Did you forget a "use" statement for "Twilio\Rest\Api"?" at /public_html/mautic/plugins/MauticFBAdsCustomAudiencesBundle/Helper/FbAdsApiHelper.php line 42 {"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Attempted to load class \"Api\" from namespace \"FacebookAds\".\nDid you forget a \"use\" statement for \"Twilio\\Rest\\Api\"? at /public_html/mautic/plugins/MauticFBAdsCustomAudiencesBundle/Helper/FbAdsApiHelper.php:42)"} []

```

Any clue where to look?

I’ve created the Marketing API app & connected to a business FB account with system user several times and all I get is the same error?
