I viewed today's Tuesday Release Video regarding that a zero inputted into a restriction field would now actual equal zero. Great!

I tested this feature using a 'Tennis Only membership' where the membership is not allowed to reserve pickleball courts.

I updated the restrictions for the 'Tennis Only membership' to allow zero pickleball courts reservations/week. (member and family). 

However a member with a 'Pickleball membership' court still add a 'Tennis Only' member to a pickleball court. So this feature is not restricting cross sport access.

Thanks
