Well i am currently new user of events booking and i cannot find option that a user can pay monthly fee for category of some events and he can register only for those so i was thinking if that is not an optiont would it work with Membership Pro?
Example:
User payed monthly fee for a plan which displays events only from a category that belong to category or more categories in events and he can register there for free only till his subscription is valid.
Unfortunately, that feature is not supported in Membership Pro and Events Booking. If you want to have this feature, there will be some customization needed !
