One last question which I forgot to ask... Now that WhatsApp works, should I keep AppGuard installed on the tablet and Blue Stacks on the laptop or I can uninstall them? I have unchecked the auto-update function, so I guess it will work without any risks?
I tested now, is secure, i uninstalled AppGuard from my tablet and i reboot, WhatsApp stay get messages and work.
Whatsapp in BlueStacks is not need it now, you can uninstall if you wanna, this is secure and better remove of bluestacks.
