Multisite and GravityKit Licenses
If you network-activate any GravityKit plugins on a Multisite network, it counts as a single activation.
If you don't network-activate GravityKit, each site will count against the license limits. You will also need to activate the plugin on each site individually.
Please note: a license is for a single person to contact support. If you run a network, each site should not contact support; they should contact you (the license holder), and you should then contact GravityKit support on their behalf.
