Functionality of the "Individual Connector"

 Hi there,

can someone please confirm the full functionality of the "Individual Connector with Google Data Studio?

How many sources can I connect with the connector and what does "the number of ad accounts ad network²" mean under the pricing model? - What are the restrictions?

Are there any limitations using following data sources?:

- Facebook Ads

- Facebook Insights

- Facebook Insights

Many thanks in advance.
