Hi Igor,

it would be helpful to have the XLS file to replicate.  There is most likely a small problem with on of the questions that the web app is more strict about enforcing than the mobile app.

JTedrick-esristaff it seems that I have found the cause. Groups with only attachment questions are not supported.

But I still do not have a solution.

I  attached just the fragment where I found the error.

Hi Igor,

We've been able to replicate the issue and will address it in a future release.
