The PlayStation Network will undergo maintenance on Wednesday.
Sony announced that scheduled maintenance for PSN will take place tomorrow, April 22. The downtime will only affect messaging services on the network.
The maintenance starts at 5am and ends at 8am BST.
During that period, you won’t be able to send, receive, or delete PSN messages. For group messages, changing the group message titles and adding new members will be disabled as well. This will affect PS4, PS3 and Vita.
All other gameplay services will be unaffected.
