@Ondřej-Šutera I tired to pay subscription fee without login but it said "You are already Premium
Your account is already associated with an active Windy Premium, valid until May 17, 2023, 07:00 AM, purchased through FastSpring.
We recommend you ask FastSpring for a refund for your newly purchased Windy Premium. Alternatively, you can assign it to a different account."
Please solve the issue as I am sharing the weather forecast to the farmers and they rely my forecast to take action on their farms.
Thanks
