Feature to prevent upload files with more than MB doesn't work in 3G/4G

Hi my team is buiding a mobile app with outsystems 11.

One of the features that is needed is to prevent a file upload if a pdf file has more than 2MB.

If i use a router connect with cable it works fine but if the router is connected thru 3G/4G this feature doesn't work.

any ideas? 

Hi Francisco,

Can you tell us how you currently check the file size? Normally it shouldn't matter what type of connection you have. And on what platform do you have this issue?
