Findmykids Subscription Paid but Premium Features Locked

I am using the Findmykids application on my Samsung S10+. I initially used the application with a 12‑month subscription. After that first 12‑month period expired, I paid 54.99 EUR again so that I could continue to use all premium features, but since this payment the application does not work properly and my access is restricted. At the moment I cannot see how much time my child spends on the phone during the day, I cannot see which applications are being used, and I cannot block applications. When I try to see the exact location and enter the detailed location screen, the application shows me a 7‑day free trial offer and then asks for additional payment again, as if I have no active subscription. Because of this, I practically cannot use the functions that are most important for me as a parent. I do not want a refund; I like the application and I want to continue using it. My request is that my 54.99 EUR payment and existing subscription are correctly recognized and that all premium functions (screen time, app usage, blocking and detailed location) are activated on my account without requiring any extra payment from me. If there is any setting or step that I need to complete on my side, I kindly ask you to clearly inform me so that I can activate all necessary functions without another charge.
