For at least two months now, I have been unable to create and save an audience in Facebook Audience Insights.
It doesn’t work in either Chrome and or Firefox, even with all extensions disabled, and the problem is present whether you use the old version or the new version of Power Editor or even the regular Ad builder.
Here’s the first report, nearly 11 months ago but there are several others in the same boat.
I know for a fact that its worked before, but in fact on this post, Haily from Facebook says that you can only save an audience from a couple of places, and Audience insights isn’t one of them.
Does saving an audience from Facebook Audience Insights work for you?
