@Sarahlou1976 Welcome to the community and thanks for posting. The parental controls feature is used to block websites. You may need to block the website that the app is accessing rather that the app itself.
This link on Parental Controls explains what you can do with it and how to manage the filters
@Sarahlou1976 sorry I misunderstood, if you send over your details we can get a fault reported. We're quite busy in the Mod team at the moment so it will be next week before we're able to reply.
You can find the 'click here to contact the mods' link by clicking on my username. If it's really urgent I'd recommend you call our technical helpdesk on 0800 111 4567.
Thank you for sending in your details. I'm sorry your having problems with the Parental Controls. I've had a look at your account and have made a few changes that should have resolved the issue. Please can you try again and let me know if this has fixed things for you?
