We are aware of an issue where mouse buttons may not bind to actions on PlayStation in Fortnite. Our team is investigating this, and this issue may be resolved in a future update.

In the meantime, you can try the following steps:

2. Plug your mouse into a USB port on the back of your PlayStation.
3. Restart your PlayStation with the mouse already connected, then launch Fortnite.
