We're sharing keys between dev and sandbox, not dev and prod. Thanks for the info!

Now, different domain are "compatible" - then can share CKDS/PKDS. You wanted to share domain, which is impossible (and that's good IMHO). Of course there another story behind,: should one share crypto between prod and dev? We just answered how it's possible, not is it recommended.
