Hello @KerDk, thank you for supporting us by subscribing to Windy Premium!
On which platform are you subscribed? App Store, Google Play, or via desktop. The restoration process has to be followed on the platform you originally made a purchase. Check the manual: https://community.windy.com/topic/11832/what-to-do-if-you-can-t-access-your-windy-premium-features
If the restoration fails, please, let me know in which step it failed and if there was an error message, what version of Android, application (found in Menu, when you scroll down), and device you have
