Premium not working on app

I bought the premium subscription and i still get ads in the app. Why is this?

Hi, could you make sure the Riot account you’re playing on is linked to your TRN account which has Premium? If the Riot name is out-of-date, please relink it.

Once you’ve linked the Riot account, please wait a few mins and then restart the desktop app.

Thanks
