I checked this with Amir over email, moving the conversation here.
We will be running a fundraising campaign in Latin America sometime next calendar year, for now the campaign is planned for April but we are working on a big tech integration for this, so plans might change.
Is there a way we can create a new language code on Meta for Latin American Spanish? The same way we have pt-br as a language code, that we use for Brazil campaigns, it would be great if we can have a language code for 'standard Latin American Spanish'. While LATAM Spanish varies between different countries, there is a 'standard version' that is accepted across countries, often used in advertising, subtitles etc.
Thanks for your feedback.
