User Sync plugin issue

Hi, I am using the User Sync plugin by WPMU DEV which works fine. However, I just noticed due to regular user complaints that if a user resets his password, its NOT synched to the connected sites.

If I reset a user password in the backend, it does work. If the reset works through the standard WP password reset function open to the frontend, it doesnt work.

I consider this an issue, thanks for any help.
