Loading Bar Stucks up in Mid While Exporting to Companion for Testing on Mobile

It was working good. Having just 3 screens and 10-12 images of smaller sizes, still, the loading bar stucks up in Mid every time while Exporting to Companion to Test on Mobile. No error pop up ever. Even mobile memory and storage are sufficient. Could anyone suggest me the reason and way out?

Make sure you have accepted the storage permission for the companion in the app settings.


Where to find this app settings in the Mobile or Creator?

Go to the Android’s Settings > Apps > Kodular Companion > Permissions > Storage > ON
