Hi ,

We are using appium-java client ( version 3.2.0 ) for running android script in appium mobile grid (1.4.13 ) . we are running multiple instance of android node ( like : [Running multiple instances of Appium server for Android and IOS device](https://discuss.appium.io/t/running-multiple-instances-of-appium-server-for-android-and-ios-device/4107) ) and its working fine .

The issue when i am sending the following capabilities and running in grid with running multiple instance of android node then getting the **error : error: Command failed: error: more than one device and emulator**

**CAPS :**  
capabilities.setCapability(“locale”, “en\_US”);  
capabilities.setCapability(“language”, "en”);

Why appium is not allowing to send the above localization caps as default ? is it bug ?

Thanks ,

Hello All ,

Any confirmation on [Command failed: error: more than one device and emulator , is it BUG?](https://discuss.appium.io/t/command-failed-error-more-than-one-device-and-emulator-is-it-bug/7027) please ?

This issue similar to : [https://github.com/appium/appium/issues/5396](https://github.com/appium/appium/issues/5396) but i am using simulator not the devices

Appreciate your help !

Thanks ,
