Technical glitches frustrate Pokemon Go fans in Chicago

A major Pokemon Go festival in Chicago to celebrate the one-year anniversary of the virtual game went badly wrong when technical glitches prevented many fans from logging on.

The problems forced Niantic, the developer of the wildly popular augmented reality game, to promise that everyone who registered for the event would get a full refund for the $20 (€17.10) tickets and $100 (€85.70) in credits for use of the app.
