Mulitsite Installations?

The free version can be used on multisites: Their limited features has no effects on this.
With the PRO-Version you can store Templates in the database for using it on multiple pages / blogentries. As these Templates are stored site by site multisite Management comes into the game. PRO-Versions prior to 2.0.9 do not support multisite. Versions after 2.0.9 are multisite ready.

Thanks to Rod from Canada and Layth from Australia!

Version 3.5.7 (July 27 2020), see in detail here:

Importaint when generating Custom Post with the Plugin, esp. when using another, nested, jsoncontentimporter-Shortcode in the templates: If this is up and running there should be nothing to do. If you start new: There is a new switch at the Plugins-Options at tab "Shortcode-Settings" called "Separate parent- and child-settings". If this is selected: the nested jsoncontentimporter-Shortcode are separated way better from other jsoncontentimporter-Shortcodes than before. This is useful e. g. for oAuth-Authorization.
