I trying to set up a framework automation setup with multiple devices with each creating an Appium server depending on how many devices are connected. I'm able to create an Appium server and assign it to each device, but when it starts and at first show the correct form of the Capabilities written for each device. However, when I start to run tests, the second server's session gets overridden and connects to the first device, and as a results, no test get run on second device for the second server.
Is there a function to keep the Appium servers stick to their assigned device and never get overridden?
Here is a bit of the logs when the session get overridden by another device:

This is what the logs showed for the driver when I ran the test:

If you are running test in parallel you need to provide the
systemPort, more details here
