Hi Monica,
Thanks for following up!
Yes, the plugins can be used on a multisite installation and you can purchase whatever license you see fit for your use, whether that is Personal or Multisite. The Multisite level license can be activated at the network level and grant automatic updates to all sub-sites within the network.
If you’re wondering whether or not you actually need a Multisite license for the plugins, it kind of depends on what you’re looking for and I would suggest checking out this article to help you decide, as it covers the main reasons why you might choose to goย with one license over the other.
Does this help clear things up? Please let me know. ๐
Cheers,
Geoff
