Resume activity force hiding other views

Hello, the problem is that if I hide the game and then expand it, the view that I add to the main window becomes invisible, although the view itself is not destroyed, but I only see the unity scene.
Adding a view using the following code:

Unity Player.current Activity.addContentView(content, content.getLayoutParams());

in versions 2020 and 2021 to 2021.3, everything worked fine, but now it has stopped, when I open the game, it even seems to me that my representation in the form of animation fades out. Someone has faced such a problem, why is it so?

Example: I added a TextView via the plugin to the main view of the unity activity, it is displayed on top of the unity scene, everything is fine. But now, if I collapse and expand the game, then I only see the unity scene, although through the code I can access the TextView (that is, in fact it has not been destroyed or removed from the hierarchy, but it is not visible).
Thank you in advance!

Solved my problem by using this code:
content.setZ(1);
