Hi there! Thanks for dropping by and taking a look at our plugins! 🙂
Unfortunately, our licenses above the Personal tier are intended for multiple independent activations and aren’t linked to each other for event syncing or other similar features. However, you might consider taking a look at our iCal Importer add-on–if there are events that you’ll be wanting to keep synced between multiple sites without having to maintain them separately, you can simply create a Google Calendar to house those events and set a recurring import on each site to keep them up-to-date. You can read more about how to set this up here!
I hope that helps! Let me know if you should have any other questions!
