Dynamic data: error in app

We’re using the dynamic data attachment for our programme. However, we have run into a problem with the app.

The first question we ask if whether the respondent have an email or not, Depended on the answer we look up in the parent survey on email or phone number. This works perfectly in the web version where we can diverse between phone number or email as the linkage. However in the App we get an error when we try to go on to the next question form the first “do you have an email”-question.

Can anyone help with this issue?

Thanks in advance.
