The issue has now been resolved. The App should now be available in the Appstore.
We are expecting to be back on the Appstore in the next 24-hours.
We are currently experiencing issues with users being unable to download the iD Mobile App from the Apple Appstore.
This does not affect the iD Mobile App in the Android Playstore or the iD Mobile website service.
If you've already got the iD App downloaded, you should also be able to log-in like normal.
We're working on getting this available in the Appstore again as soon as possible.
If you've not got the app downloaded or wanting to register for the first time, please use our webservice via https://my.idmobile.co.uk/ to manage your account whilst we work on fixing this.
