[Ionic4] Is it lazy loading?

I have well over a dozen pages in my app and things work - most of the time. Sometimes, especially when I load a new version, the first time I click on a page, it doesn’t load it. But later it does. I assume this is due to lazy loading.

I checked and in the app-routing.module.ts, I have the preloadingStrategy: PreloadAllModules. I would assume that this would preload the modules but doesn’t appear to be working.

Is there another way to FORCE it to preload modules at the beginning?

You can definitely do some custom preload strategies with Angular:
