True African Art
I used this app for about a year and with all its menus, bells, and whistles, most of the program focuses on ads and bot messages.
We have never paid for an add and through experience, find bots to be well, robots, not humans who can customize content live.
We did get about 200 new subscribers, but with our Facebook Page, that is minimal. The widgets/plug ins they have for your site seem to get in the way and there are just too many of them that it can interfere with the experience your client is having on your site with a constant call to action to go to Facebook Messenger instead of our website.
The app seems to be in cohoots with Facebook to get you to spend money on ads etc. in promises that it will lead to more sales. It may lead to more sales, but doing it for free won't get you anywhere, and there is no guarantee with the ads.
Sorry Facebook, but you will fade away in becoming too big.
