Despite the 14-day trial period, the account was debited at $50, so how is it after all? Free trial period, or payment for a service that still does not work properly because it had a problem generating a basic chip with 2 sensors, a display and a microprocessor. I would ask for a refund, I am unhappy with the results of the application, especially since later I had to do it myself, and I was charged for the amount, as for a good, working project.
