I've been most successful in getting reviews and feedback only when triggering a cta at the appropriate time and to the appropriate user. For example, figure out what a valued user means to your b2c product, is it someone who has done x over a specific period of times or logins.

Once you determine that, try showing those users a modal that says something like, are you enjoying "my product", with yes and no answers. If no, ask if they would like to provide feedback so you can make their experience better. If yes, ask if they could rate your app.

I've found that by using this method you, a) show the cta to users that matter, b) get feedback from frustrated users, and c) get positive ratings from people who have expressed a positive intent.
