Hey, @rutger_3146. Welcome to the Lightroom community. I reviewed your account for the community and found no active subscription or transaction for Lightroom.
The respective app store manages subscriptions from the mobile app store. If you've already been charged, you can contact their support channels. Check this page for help with managing your subscription to the AppStore: https://adobe.ly/40WLltM
This should help. Give me a heads-up if it does. Thanks!
