We are aware of performance issues on some devices running iOS 11.2. These issue have affected sellers in different ways such as app slowness, freezing or glitchy behavior. Our engineering team is actively working to diagnose and fix this issue, but we do not have a full resolution at this time.
In the meantime, we have been able to verify a quick troubleshooting step you can take to get your devices back up and running.
All you’ll need to do is restart your Square Point of Sale app. You don’t need to remove your device from the Square Stand or restart your entire device.
We greatly appreciate your patience while our team works to get this resolved. We will continue to update this article with any new information we have.
