I've updated to EasyStore 1.2.1 - which apparently fixes a method for GUEST accounts to view their orders... Only it doesn't!
The Option is there on the confirmation page (see: https://prnt.sc/bRYw6XNXphLr), but the significant fxxx up is that this links to /shop/myorders which IMMEDIATELY redirects to the Joomla login screen!
How exactly is a GUEST meant to log in to Joomla????
