Anything else relevant?

The resolve data from the parent can still be accessed as

class ChildResolver {
  resolve(route) {
    const parentData = route.parent.data;
    // ...
  }

but this looks like a hack

but this looks like a hack

It's not, that's intended. If you want the data (and some other things) available across all routes, you can use paramsInheritanceStrategy: "always" in your router configuration:

Defines how the router merges params, data and resolved data from parent to child routes. Available options are: […]
– https://angular.io/api/router/RouterModule#forroot

still not working with paramsInheritanceStrategy: "always"
this does not look like a needed option :

'emptyOnly', the default, only inherits parent params for path-less or component-less routes.

my parent is a component-less route and the resolved data works as expected in child component - the problem is in child resolver where the parent data(only resolved) is not available

I'm sorry, my bad, I misread that you're in a resolver yourself.

We have a number of feature requests for this behavior. It is as intended currently though, and not currently on the roadmap to add as a feature due to other priorities taking precedence.

Sorry I don't have better news on this one.
