Written by Rakesh
Updated over a week ago
From 3.0 onwards, spotipo follows per site licensing. This allows a customer to run a mix of Free/PRO/ENT sites on the same Spotipo instance.
A site in Spotipo represent a physical location or a network of WiFi access points.
A site can have only one landing page, if you want to have multiple landing pages per physical location, group APs into different sites.
