When an update for Rocket League is released, you may see an error message when trying to queue for a match saying "Version mismatch. Please get the latest version of the game."
If you see this message, please download and install the most recent Rocket League update and you should be good to go!
The easiest way to trigger an update download is to restart your console or Steam. Once restarted, the update should happen automatically.
To completely restart Steam:
- Click on the Show Hidden Icons icon in the lower right hand of the screen
(it looks like a chevron or up arrow)
- Right-click on the Steam icon
- Select Exit
- Wait a few moments
- Launch Steam
