Hello,
This only occurs on iOS17 with custom image added. If you remove splash than its working

I did this without splash and had the same results that the screen is blanked out.

Help me understand. When I call enable() is it supposed to show the privacy screen immediately? The documentation suggests that you use enable to protect against screenshots and view in the switcher if the user tries to take a screenshot/use the switcher. So, enable() = "wait until a screenshot is taken or the switcher is shown and then show privacy screen". Right? Because when I call enable() it IMMEDIATELY blanks my screen, which seems incorrect to me.

But, maybe I misunderstand. Do I need to add listeners and then only call enable() when the listeners are triggered? "enable" to me != "show". It "enables" protection.

Here is a screen recording where I show it disabled first, then enabled second, all without imageName specified in the config (no splash)

(Oh, and the docs don't really show how to specify a splash image. What size is used and how is it scaled? Do we just put it in the app's asset folder and then just give it the plain name to it? imageName: 'my-privacy-screen.png' if my-privacy-screen.png is in /assets?)

On this video you posted it is working as it should. They grey screen you get it is because you didnt add splashscreen. The privacy screen is visible only when app isnt active (in recent).

If you put img name splash, than it will use splash screen of the app if you have one. I generated splash screen with capacitor-assets plugin.

Yes, it does seem to be working for "recents"/"switcher". But it's NOT preventing screenshots. I couldn't care less about the switcher. I NEED to prevent screenshots. How do you prevent a screenshot with this plugin?

I will take a look at it in the next few days.
