I have an odd issue on iPhone - have updated the mobile app and it fails with the following. Any hints would be useful here please! 

 

Unable to connect to iD Mobile

Error code:

The operation couldn't be completed. Failed to create a block of data that demonstrates the legitimacy of the app instance

('generateAssertion:clientDataHash:completionH andler:"); keyld.length = 44, clientDataHash = FmHcFrsnJQAPrXAPSkhRB1nrKNzO/XUcQ6l/9st7WV8, systemVersion = 18.1.1: DCErrorInvalidKey - An error caused by a failed attempt to use the App Attest key.

    Hey there ​@chromoweb, we’re sorry to hear that. Have you tried deleting the app and re-downloading it?

     

    Are you able to login to the website?

     

    Thanks,

    Tyler
