When you use the Edit Status button, the Modified date does change so IMHO it's inconsistent if the status update from the payment provider doesn't update it.1) not sure if changing status should change the modified date of order itself
3) The $app->enqueueMessage is displayed by Joomla, so it depends on template, how it is displayed. Can you paste a screenshot of this?

Here I selected the last part of the text only. As you can see first part is invisible. I haven't tried with Cassiopeia out of the box, I was using your template.
Maybe another Dev request then? Because when an order is (partially) refunded, it should also be covered in the totals and reports/statistics.4) For now, Phoca Cart does not handle refunds, it only can change the stock e.g. if the good are returned back, etc.
Thank you
