Can I use Metal and Bounded at the same time in one scene?

I am creating a hybrid app where the Metal Volume displays the main content and the Bounded Volume displays buttons and other GUI.
I have confirmed on the actual device that it is possible to display one Metal Volume and multiple Bounded Volumes.
However, I felt that the behavior was unstable, such as the app crashing when transitioning from a scene with only Bounded Volume to a scene with Metal + Bounded Volume.
Is it officially supported to use Metal and Bounded at the same time?

I believe this is something we’d like to support, so when you experience crashes, it would be great if you could submit bug reports with repro cases (and ideally, report them here with the incident numbers: IN-#####) so that we know what we need to fix to get it working. I’m not sure how much we’ve tested this particular pattern internally.
