Progress not working in packaged game

Hello, Thanks for your plugin;
widget loading progress works great in editor but in packaged build, progress stuck at zero and the throbber in my widget does not move either, but level loads successfully.
I putted one frame delay between "Create Slate Widget LPT" and "Open Level LPT" to be able to see the widget.
(Tested Windows and Android package using UE 5.7.1)
