Some users of Applie iOS devices have discovered that they cannot access the June issue of Digital QST. Instead, they are presented with a message stating that there has been an “Authentication Error.”

The problem is due to a software issue at the service that creates and provides the digital edition for ARRL. It has now been resolved.

However, you must clear the cache within your Digital QST iOS…
