Hi,
Please make sure you have followed this document Execute mobile tests with Appium 2.x in Katalon Studio (PoC) | Katalon Docs. And as mentioned in the docs, If you are using Appium 2.0 and Xcode 14 to run mobile tests with physical iOS devices, you need to manually install WebDriverAgent..

Hi @Elly_Tran ,
as from the link you attached, we should use Appium version 1.x.x. So we can’t use Appium 2.x to run mobile tests with Android?

Hi,
I do not think so because in the note of this part [Mobile] Configure Android Studio (Emulator) in Katalon Studio | Katalon Docs, we recommend the latest Appium version.
You just need to install the compatible Appium version with Android version and Katalon version you are using.
Hi @cyntiaverolita,
We are delighted to inform you that Katalon Studio version 9.1.0 has just been released which also brings support for Appium 2.x. You can learn more in our announcement topic below: 
http://forum.katalon.com/t/new-release-katalon-platform-update-nov-30-2023/109054?u=albert.vu
We will also proceed to close up this topic. Should you encounter any bug whilst using KS 9.1.0, or have any other questions, feel free to create a topic in #feedback-reviews:bugs-report or #product-forums:katalon-studio
Thanks, 
Albert from Katalon Community team
