How can I set up a subscription on my website so that customers gain access after purchase?
Bold Subscriptions does not provide website access control based on subscriptions. To achieve this functionality, use the Bold Memberships app instead. This app allows you to create membership plans and restrict access to specific website content based on membership status.
