Conversions status
Jamroom Developers
conversions are added tot he queue and are processed behind the scenes, so the user will not still be on the screen when the conversion is happening.
Any error in conversion will end up in the error log for the admins to see, you could tap into that process if you wanted to setup something custom for your users.
Better would be figuring out why conversions fail and make it so they dont fail i reckon.
