I received an email recommending an update to the latest iOS in relation to the Square POS API.  
However, our app uses the [Point of Sale SDK](https://developer.squareup.com/docs/sdk/point-of-sale/ios), and we are particularly concerned about the impact on iOS 18 and Square iOS app versions below 6.5.0.  
Are there any issues with the POS SDK under these iOS and app versions?

The Square Point of Sale SDK is designed to be compatible with the latest versions of iOS. However, it’s always recommended to test your application thoroughly when a new iOS version is released to ensure there are no unexpected issues. As for the Square app versions, it’s always recommended to use the latest version of the Square Point of Sale application for the best compatibility and performance. If you encounter any issues, please report them to Square’s developer support for further assistance.
