can't change session_store options

[francescob]

Steps to reproduce

in an initializer try to set
Rails.application.config.session_store :active_record_store, :key => '_my_app_session'

or in application.rb

config.session_store :active_record_store, :key => '_my_app_session'

Expected behavior

session store should be set to active_record_store and key should be called _my_app_session

Actual behavior

both session store and session key keeps default values (CookieStore)

System configuration

Rails version:
5.2.1
Ruby version:
2.5.1

Sorry, the problem seems to be with RailsAdmin gem. I'm closing this.

I'm having the same issue without RailsAdmin.

I'm setting in development.rb

session store

config.session_store = :active_record_store, {
key: Rails.application.secrets.session_key,
domain: Rails.application.secrets.domain,
}

But after app loads, my values in
Rails.application.config.session_store
are default "key' and CookieStore

I'm using active_admin, not sure if that plays any part
