Currently, there's a hard 30-day limit for all trial users in a White Label trial, so if you have an active WL and would like to offer your trialists 30+ days in their trial (e.g 40 days, which is an extra 10 days) you're unable to do so.

It would really help if I had the option to offer my trialists additional days on their trials before they sign out, and I am unable to do this at the moment.
