Question How do I debug the IronSource Demo Scene, which isn't showing ads?

I'm trying to migrate over to LevelPlay because of Unity Mediation shutting down. I've gone through the migration guide and wish to ensure that my IronSource ads are displaying. With Unity 2021.3.29f1 and the platform set to Android, I gave the IronSource DemoScene (from the LevelPlay Unity Package) my Android's app key from the IronSource Ad Units & Placements webpage. Two problems occur when I do this.
1: If I try to run my MSVC debugger while playing this demo scene, Unity freezes even though no breakpoints have been hit. Once I unhook the debugger, Unity proceeds to run again.
2: Trying to initialize and show any of the ads simply returns as "false" and no ads show.

How am I supposed to debug this problem? It seems like the initialization is failing but I don't get any messages stating as such, merely the fact that the line of code ran.
