This update is quite horrible. This should nI updated it on my own agency site. The update went OK as I have a relatively small number of of transactions. My CRM takes care of 99% of invoicing.

I had to wait on other plug-ins to catch up to 4.0 compatibility so I only just updated a client with a small number of transaction. The update took so long that that the server went 500. OK... The dashboard would not populate. The front-end was super slow. I was forced to roll back to 3.9.3.

The server meets the Woo requirements. This should not have happened. I'm reluctant to "upgrade" any other clients as they are are all much larger.

I discovered that there is now a plug-in to disable the WooCommerce Admin bloatware. This is reminiscent of Classic Editor vs. Gutenturd. I'll give the plug-in a try but really, we shouldn't have to.

I've been developing WP sites since Kubrick. Things started going downhill with Jetpack. Gutenberg was a pant load, now this.
