I had Zephyr Scale already installed and running, but it stopped working saying that the license was invalid. So I tried starting a Free Trial, but only got a PRODUCT_ALREADY_ACTIVE error message. So I tried uninstalling the app and reinstalling (by starting a free trial), and I get an error message saying to confirm payment details and license status.
I checked the response to the http request, and it returns the same PRODUCT_ALREADY_ACTIVE message, with subcode "connect.remote.upm.install.payment.failure.exception".
