I can access them as expected (this.$f7route.context.objTest, etc.), just not when passing via .navigate. I would have expected it to work in the same way.
Final solution for anybody wondering, I had put props in my router as well as the target component. That was causing the issue. I only needed it in in the components, not the router. Thanks so much to @nolimits4web for an awesome framework and being so helpful!!!
