Why are the buttons not being pressed in the downloaded game on Google play, but everything works in Unity?

Question

Unity

Such a problem, I posted the game on Google play, and the buttons are not pressed in the game itself, but everything works fine in Unity.

Answer 1

most likely not all the necessary components on the Event System are attached. Or on canvas.
The raycasters may not be configured correctly, or the Event System .
Smoke manuals,

Answer 2

If the project uses Addressables, then its Default Build Script must be run before each build for a new platform. I could forget before building for Android and something did not get into the build.
