Proxy is set to your virtual machine and not for apps. Whatever proxy You set it will be used to work with any apps in this Virtual Machine.
But it does not mean You can use many accounts with the same app while using different proxies.
If You want to use different accounts You have to use different Virtual Machines.
and can you tell me why I have a virtual machine turned on
ip check app shows IP change
and in chrome it shows my original IP
How should I understand that?
I tested with Chrome app and default browser and could not reproduce the problem.
So, please tell what app you check IP and what proxy you use, give example in pm.
