El código stub (la parte del código que se integra en tu sitio web) incluye automáticamente compatibilidad con IAB TCF v1, IAB TCF v2 e IAB USP. En algunos casos, la compatibilidad con IAB TCF puede causar problemas. Para evitarlos, puedes reformatear tu código stub de la siguiente manera:

1. Cambia la línea window.gdprAppliesGlobally a true si quieres utilizar el TCF a nivel global. Si quieres utilizar otras legislaciones fuera de Europa, quizá te interese establecer el valor en false.
2. Elimina la línea que incluye la palabra __cmpLocator para eliminar la compatibilidad con TCF v1
3. Elimina las líneas que incluyan las palabras __tcfapiLocator y __tcfapi para eliminar la compatibilidad con TCF v2
4. Elimina las líneas que incluyan las palabras __uspapiLocator y __uspapi para eliminar la compatibilidad con IAB USP
