If you are still seeing ads, it might be that you are not logged into the account the subscription has been purchased with. But instead are either into another account or not logged into any account.
Firstly try to log in. If you are already logged in then try logging out and then in again. Also, try to clear your cache as an additional step.
For users who have an account from Google Play or the App Store and are seeing ads on the website, you will need to create an account if you do not already have one. You can do this in the app. Then try logging into the website with this account and your subscription should be reflected.
If you are still experiencing issues, please contact us at support.
