Membership 2 Pro Memberships Not Expiring

Hi,

Have another issue on Membership 2 Pro where memberships that have a limited time are not expiring automatically.

If I go to the All Members screen, view details about a membership and refresh the status, it will move to expired status as it should, however the cron job does not seem to be doing this itself.

Not sure what information I can provide to assist with this...?

Is this a known issue?

Thanks,
