PlayStation Europe suspended the "redeem voucher" functionality on the PlayStation Network today after users reported service disruptions, according to a post on the PlayStation Blog.
The company announced yesterday that it would be switching off a few features for European PlayStation 4 customers on day one, and that these features would be switched back on once the "intensity of launch day calms down." The two features are "What's New" (a feature that allows users to discover and engage with their friends' PS4-related activities) and "Content Information Screen" (a feature that allows players to see friends' activity and information specific to a title.).
The announcement today of the "redeem voucher" functionality being disabled means that money cards, product vouchers, PlayStation Plus vouchers, PS3-PS4 upgrade vouchers and any other voucher for digital content are not redeemable at this stage.
Sony Computer Entertainment Europe's blog manager Fred Dutton apologized for the inconvenience and said that Sony is currently investigating the service disruptions and will provide users with an update when more information is available.
The PlayStation 4 launched in Europe today.
UPDATE: Some PSN users in North America are reporting that the 'redeem voucher' feature has also been disabled for them. The official Twitter support account for PlayStation confirmed the suspension of the feature below.
