There’s a lot of conflicting info about using APO with WP-Rocket right now. It seems to me that WP-Rocket has quite a few features that APO does not. Things like JS defer, lazy loading etc. Would be nice if they played nicely together, or if APO became a one-stop-shop solution.

Is anyone successfully using WP-Rocket and APO?

I run WP-Rocket on sites hosted by Kinsta, and this means the actual caching is already being handed off to Kinsta’s own cache plugin. So for me, WP-Rocket is used for all the other optimization features.
