@AISFR95 If you want to get the invoice from your subscription, it depends on the platform you used for the purchase:
Mobile app via AppStore or Google Play: you have to handle that on your own in these stores
Browser version of Windy via Fastspring: you can access your subscription management here on this link https://windy.onfastspring.com/account and get the invoice there.
Browser version via Paddle: you can access your subscription management on https://customer-portal.paddle.com/login
If you have any questions, please let us know.
