Installation was straightforward and the plugin works great. I struggled with getting my access token to make it work, but the developer was there with incredible customer support the whole time. He also graciously helped me add an additional filtering feature that I needed for my use case.
p.s. In the end, my access token issue was related to how my account was set up and had nothing to do with the plugin. I needed to authorize access with a user with direct access to my page - not one authorized via the business manager. Everything was a breeze after that.
