Hi Carsten!
Since our Aggregator product is not actually a plugin, there is not a “Multisite License” available. Instead, Aggregator uses a combination of number of imports per day and number of sites it can be used on.
The personal and community licenses can be used on up to 10 individual sites, and the event hub license can be used on up to 100 sites. We also have an unadvertised license for 300 imports per day and up to 100 sites.
To activate your Aggregator license on individual sites, just enter it in the licenses tab on the sites you wish to run it on.
Hope that helps! Please let me know if you have any further questions about this.
Thanks,
Sky
