Hi @adam20,
Welcome to the Auth0 Community!
I have just checked all of your tenants under your subscription account and found that none of them have the Force a password reset after X days Action deployed and bound to the Post-Login Action flow.
Could you please make sure that you have clicked on the “Add to flow” option? You can do this by going to the Auth0 Dashboard > Actions > Library and clicking on the triple-dot icon and selecting “Add to flow”:
Please make sure to click on “Apply” to save your changes once you have added it to the Post Login flow.
Thanks,
Rueben
