Hello,
First of all, thank you for your purchase.
Because the plugin uses NewsAPI to import content it generates, there will be some restrictions in the importing process, because of this.
NewsAPI provides category based importing – but only at once, from all the wide variety of websites it supports. Also, they provide keyword based search, to filter content imported from their service. However, they do not provide category based search from inside a specific news source. To make this work, we can use keyword search, though.
So, the best way to import content on a specific subject from a specific news source is to use keyword search.
I just created a tutorial video, to show how this can be done. Please check it here:
