Issue with plugin and Stripe checkout

Hi,
I use this plugin on a number of sites.
Today on this site the plugin would not allow me to empty cache and was blocking payments with Stripe as the card detail form was not displaying.

After simple debugging I found the issue was Autoptimize conflict so I’ve deactivated it.

We like your plugin, how can we resolve & re-activate?
