Issues fully updating a collection based on a complex gallery

Hi,

 

I have built an app that uses the data within a gallery to download in excel using a collection.

 

However, as the gallery uses lots of data, consists of lots of formulas, and it relies on a number of dropdowns it is very slow.

 

Unless I scroll through the gallery, after the 10th item, the rest of the items just copy the values from the first item.

 

I have tried to add in a timer to delay the download working for 60 seconds, however this makes no difference and the only way to update the other items is to scroll through my gallery.

 

Does anyone know how to automatically update my collection for all items without having to scroll through my gallery.

I have now found a work around solution to this.

 

I have duplicated my gallery and set all width/heights to size '1'. This allows all items to load when the screen opens (although it is a bit slower to open) and the collection now updates properly. I then set the gallery to not visible, and the other gallery will appear instead.
