Customer Complains of High Bandwidth Usage

I deployed an SC app to a customer and they are complaining that is it using far too much data. A lot of their staff use their mobile data allowance to access the app.

HHas anyone tackled and solved this problem? I think I did some gzip settings (or similar mumbo jumbo) on my server but obviously its not enough. Grateful for any suggestions I can get.

​Thanks in advance.

Do you have grids that loads a lot of data but does not display like page 1 of xxxxx? It will move all the data to the client if you are not careful. But besides that I wouldn’t know actually. I have some ‘apps’ out there, but never had this issue reported.
