PowerBI Pro License Doubts - AutoRefresh and Dashboard Sharing

Hi SaCvP125,

• We can only use the auto refresh 8x per day but if each user click on the refresh button it will make an update of data?

Yes. 

• I want to send report A to my organization and the other to my customer.

There are several ways to share reports with your organization members and customers. You could have a look at below articles:

How should I collaborate and share dashboards and reports in Power BI?

Share your Power BI dashboards with coworkers and others

• Can I share the report A on PowerBI Service and ensure that my customer don't see report A using PowerBI Pro?

If you don't share report A with customer and give access to them, they won't be able to view report A even they sign in service with Power BI Pro license.

Best regards,
