Do I have to pay now?

I signed up for Netflix today and chose a plan. Then it said I got an upgrade and now only pay 12 euro for the best rate. I couldn't vote that out. Am i paying for it now? Because without this upgrade I have the 30-day test mode without paying

Netflix gives you Premium for the first month, after which you can simply choose whether you want to keep Premium or have the Standard tariff.

In the first month you only pay for Standard.

Thank you 🙏🏻
