Can you post a screen shot of the screen with the error message?

Is it the pass number or the passport number that is the problem? Can you post a screen shot of the screen with the error message?

Hi Anna, its at step 3 when you need to enter you passport number. I am inputting the 9 digit passport number from my UK passport, 

I cant post a screenshot at the moment but it says:

Something went wrong

Please try again or contact customer service.

I have sent an email but no idea how long it will take to get a response. 

Thanks 

It is working now! Deleted the app and reinstalled it. Thanks
