Hi Karen,
Kindly find my response for your inquiries below:
I am having issues trying to setup a News feed import. I want to import everything over as it stands in the main blog however it is asking to me to add the feed to a category. I don't want to add it all to one category, I want it to import all the categories and the posts that are within them so it is all identical?
I see, if you want each blog post have the same category as per your imported feed's site, unfortunately, it is not possible
Where as per feed url, it will assigned to single category.
Perhaps, you can use other workaround suggested by ssnobben above to set up a Joomla multisite master/slave sites
I have also set up a quick test and when I click the Test Import button I just get an error of "There is nothing to be imported from the remote site currently"?
I am not able to access your backend as it shown

By the way, may I know the feed url that you try to feed import? so that I can try it locally
Thanks for your cooperation and understanding Karen
