Force user to reset password in hybrid

Hi, we work in a hybrid environment at the moment, and it has been discovered that if you are using classic AD and reset a user's password and leave the tick-box saying user must change password at next logon, the password reset works!  But, if you were to select the tick-box with the intention to make the user change their password, the password does not get reset and the user never gets asked to reset their password?

Also, if you try and reset the user's password on AAD, you get the following error message:

Because we cannot force the user to reset their password by AD or AAD, we have to tell the user to do it themselves by the classic Ctrl-Alt-Del method or set their personal password for them over the phone.

So, what my question is, is why can I not force the user to change their password from either AD or AAD?
