I think it depends how you did the the purchase.
When you purchased over the website with paddle, you have to use paddle again - or when Playstore, then Playstore. Please let us know if it works.

This issue can happen if there is an issue with your existing payment method. Usually credit cards expire after some time.

If you used Paypal the subscription agreement between Paypal and Paddle are sometimes cancelled.

You need to update your payment details them at Paddle. You can use the update payment method link in your account here: https://kurviger.de/account/tourer/en

Was genau hast du denn probiert und was genau hat nicht funktioniert? Ohne genauere Infos ist es schwer zielgerichtet zu helfen.
