The network has been down throughout today so that might have something to do with it

Hi @Amy Young We had experienced some issues yesterday with our network, but this is mostly fixed now. Additionally, as a knock on effect we have experienced a higher volume of contact than usual. The iD app has become unavailable again for some customers. We apologise for any inconvenience you’ve experienced, and we’ll continue to provide updates here - https://tinyurl.com/3ykh4ayb Thanks.
