Upload button not doing anything when clicked

I’ve got a UPLOAD button, when clicked on Android, all of our users are saying nothing is happening - no option to choose photo from gallery etc.

Please help me asap.


I take it no one is interested in helping me?

Hey Robert,
I know the team was looking into it. This seems like a specific issue to the embedded android system browser which is used when clicking links within Facebook.
Let me follow up with them tomorrow and get back to you.

Okay sounds good Uval, look forwards to hearing from you.
