Thanks to anyone reading.
I am trying to get a repeating group to fill a page no matter the height for a chat application. I attached photos of my problem. Basically the repeating group does not fill the page when the height of the page changes. Does anyone know how to do this? I have tried stretching just the repeating group to the top and bottom. I have also tried putting the repeating group inside a group and stretching that to full page. I still end up with these huge spaces based on page size.
