I’ve got a month to month subscription for Unity Pro and I’m about half way through my 12 months of UCB Pro.
If I cancel my month to month subscription and buy a Unity Pro perpetual license, does this give me an additional 12 months of UCB Pro?
Could you please contact support@unity3d.com and reference this forum thread?
