Root case: SKStoreReviewPresentationWindow was kept in KEY_WINDOW. As result, it's dealloc wasn't called and sadly iOS15 has logic to triger code to pick another key window in SKStoreReviewPresentationWindow.dealloc.

This change might break some project that doesn't strong keep windows somewhere in AppDelegate

Can't this be done without breaking backwards compatibility? (see comment). Perhaps with a configuration option or something?

I don't think it's good to potentially break any project just to fix those which use SKStoreReviewPresentationWindow.

@guillerodriguez I believe there is not much such project that doesn't keep window and relies on workaround I've removed.
anyway lib-gdx is not affected. in any case every release introduces some amount of breaking changes adopter have to adjust to.

well, not every Robovm user is using libgdx..

Will it be at least documented somewhere?

Can the example project get updated accordingly?

@MrStahlfelge it was all time like this

Okay, sorry! I had it different in my project and thought it was copied from the template.
