An user doesn´t want to wait long for a form to load. I think that 10 seconds is an accaptable time for a form to load. I have discovered that the loading time differs between iOS, Android and Windows (PC). One of my form takes 11 second to load on iOS and 45-50 seconds on Android and Windows. The hardware on my Android devices is brand new (Sony Xperia z5) and my windows computer is powerful.
It must be some difference in the code that causes this big differences. Have other users experienced similar behaviour and do you know if it is some elements in the form that is known to cause slow loading time on Android and PC?
