The feature is available in the newest MDC version for both android and iOS devices so be sure to update your MDC app. To see how the feature works in MDC Portal and on your smartphone device check the video below.
Additionally, this video blog covers steps on how to copy a custom form to a new layer in Map Editor you want to collect the data into.
