Questions

Dear @timkf18,
Thanks for posting your question

Currently this plugin when active will

1. Completely remove payment system from woocommerce
2. Completes Order without Payment

Currently this plugin does not support User Capabilities and Roles. If you can give more detailed description of the feature with “Ability to work with certain logins” I will be happy to provide this new feature in new version soon.

Thanks in advance

Thanks @omileb

For using this plugin and reaching out to put your query.
Currently, this plugin just removes the possibility of payment and completes the order i.e. the order has been successfully completed.
Since the order gets completed that is why the customer may be able to Download the files.

There can be many possibilities depending upon the scenario

The code below might work if you place in your theme functions.php but I advise to test on Development before using this on Production

add_action( ‘woocommerce_thankyou’, ‘woocommerce_thankyou_change_order_status’, 10, 1 );
function woocommerce_thankyou_change_order_status( $order_id ){
if( ! $order_id ) return;

$order = wc_get_order( $order_id );

if( $order->get_status() == ‘completed’ )
$order->update_status( ‘pending’ );
}
