If you have a PlayStation 4, there is a good chance that you have installed a patch. This patch is usually called “Patch 1.50” or “Patch 1.51”. If you do not have a patch, then there is no need to worry. However, if you do have a patch, then it is important that you delete it. To delete the patch on your PlayStation 4, go to the “Settings” menu and select “System Settings”. Then, select “Update and Security”. Finally, select “Delete Patch”.
