Customers using the new-look storefront have complained about slow loading times and wallet errors since its phased launch on October 17.

"The phased launch of the new PlayStation Store has been temporarily postponed in some territories as teething issues related to the global roll-out of the Store are being addressed and resolved," a Sony spokesperson told Eurogamer.
"It is really important to us that the best possible Store experience is delivered and we appreciate your patience as we resolve these matters."
The redesigned PlayStation Store is currently live in Australia, UAE, India, Israel, South Africa and parts of Europe.
Announced last week, the store will become more visually oriented and carousel-based to make it quicker and easier to browse.
Moving away from the original Blue colour scheme, it will make better use of the entire screen to show a broader range of content, and will effectively scale down for standard definition TV sets.
The search function has been overhauled, offering a "tumbler" style text input and a reductive list of options based on the number of letters typed.
Meanwhile, Vita and PSP content will be displayed separately to content being sold specifically for PS3.
Finally, grouped content will be available, displaying demos, full game downloads, themes and DLC around a single franchise, such as Call of Duty for when searching in relation to Black Ops.
PSN went offline on Monday in preparation for the store update.
Several new features for the PlayStation Store are being introduced in 2012, including the launch of PlayStation Mobile and PS Plus coming to Vita next month.
