I need to use same component on two different routes, and I am reusing both routes. I am following this example:

I am implementing router reuse strategy to reuse a component on multiple routes. The reuse is not because it’s the same component but because the user will a lot of interactions with it, and I need to preserve all the states, data, etc.

I am trying using it for the first time. I am using this example as a stating point:

I have a route with a CanActivate: [isEmployee]. I’m testing this for falseness. It keeps redirecting to “” and then getting stuck. Header/footer prints, blank body. https://localhost/foo => https://localhost with no trailing slash.

Using angular 13, I’m working on a page that has a dashboard of list of tiles for each user project. When the user clicks on the tile, I route to an inbox for that page using a router-outlet. This all works.
