I have numerous text fields within my form that have the same property name. This was done to have the information entered only once and that information replicates throughout the form. In Acrobat and Reader (Windows), this feature works as expected. However, when the same form is opened in Reader for iOS, each of the fields with the same property name do not indicate the values in the first named field.
This is a known issue in our last release. The details are described in this forum thread:
We're actively working on a fix for this issue. If you have a sample form you could share so that we can ensure our fix covers your form as well, please email it to email@example.com.
Thank you for reporting the issue.
