Stats fm plus doesnt work

I bought it 4 days ago even apple store shows me that i have subscription till 2025 I have received a mail aswell but it still doesnt register on the app.

I want it to work or i want a refund because this is basically scamming and a weird bug to happen even when i try to buy it again the app says you have it.

Than where is it? I hope you can help me with this.
