How to obtain 'Like, Follow And Obey' skins now?

I’ve just started to play the game around July this year, I wonder how can I get these skins now because nothing is showing up after I did the steps (Toggled the email boxes and verified my account)

Check if you have them listed in rewards history in SHIFT menu/site. If still nothing after 24h, contact shift support.

By verifying your account you mean that you (also) changed the date on the “Age group” of your actual birth date in the “Profile” menu? Because by default it sets to 2021. If that is not set for the right date, it might cause some errors and eventually the skins won’t show up because of this.
