How do you translate the tokenized string?

@weseze, Can you test the MR that I just created? Please clear your cache after applying the patch and then you should see the field formatter settings display in the configuration translation for the entity view display (/admin/config/regional/config-translation/node_view_display for nodes).

I only get a fatal error at "/admin/config/regional/config-translation/node_view_display".

Seems like this has nothing to do with the issue here?

I'm not sure if the route has changed in Drupal, but go to where you translate configuration on your site. With the updated code, you should be able to translate the entity view display configuration for the entity you have the estimated read time field formatter displayed.
