Very good plugin

Very good plugin,
There were some problems after the latest plugin update.
Refer to the solution of the friend above,
Solved the problem I encountered.
Big thanks
In lib/controller/class-order.php at line number 194, it should be $order = wc_get_order( $post->ID ); instead of $order = wc_get_order( $post->get_id() ); because it is throwing error : Error message: Uncaught Error: Call to undefined method WP_Post::get_id()
