To make things clear I’ve decided to contact you directly.
As I’ve mentioned previously, you’ve subscribed to WhatsApp Chat Basic plan that allows you to create 3 WhatsApp Chat widgets, but not using 3 different apps.
For Google Reviews, on the Lite plan, you can create just 1 widget. If you need more, you can either get a paid Google Reviews plan or upgrade your WhatsApp Chat subscription to the All Apps Pack giving the access to all Elfsight apps.
Please let me know if this explains things or if you have any other questions
