Ue4.26.2 apk not working well

We have a neatly packed mobile game project. When we run the project on the device with the launch button on ue4, it works fine, but when it is packaged as apk and tried on the device, there are some features that do not work, for example, it cannot “cast to”, data tables cannot be accessed. I would be very happy if I could help you with this. I will show you with photos.

1 - This button will play an animation in the ui settings widget blueprint and in the ui main menu. but it doesn’t work on the phone

2- here, there are 3 stages and this stage information is on the datatable. but it never spawns them on mobile
