Hundreds of soccer fans in Qatar struggled to retrieve their digital World Cup tickets today as problems with Fifa’s mobile application stoked confusion and frustration at the tournament for a second day in a row.

A line of distressed fans snaked outside the main ticketing help desk in Doha, with many reporting that their tickets had abruptly disappeared from their phones and could not be retrieved— a glitch that caused hundreds to miss the start of England’s match against Iran on Monday.

In front of a sign marked “ticket resolution point" at a convention centre in central Doha, fans swapped stories of ticket troubles and showed volunteers error messages on their mobile apps. A security guard admitted it had been difficult to control some angry fans when the crowds peaked earlier in the morning.
