I'm working with Google Analytics and i've come across a (not set) issue with Content Grouping. I changed my URL's in the month of August, and then most of the URL's went into the (not set) Content Grouping, instead of its specific group. Is there anything I can do to have the URL's put back into their correct grouping?
Also, i'm reporting out this data via Data Studio and I was wondering if there was a query/filter that I could use to have it be grouped into the correct content grouping?
