My iPhone with iOS 18 crashes when pressing the button to buy EasyReader Premium

EasyReader on iOS 18 devices can crash when pressing the button to buy EasyReader Premium, if you are not signed in with an account in-app

A fix for this issue will be available in a later update to EasyReader. Until this fix is widely available, the current workaround is to create a Dolphin Account and log in with it, followed by pressing the button to buy EasyReader Premium again.
