Problem with the widget : Device Selector

Hi…i use the widget “Device selector” in my project.I have 2 devices with this auths :
Auth Token for device ‘arduino2’ : *******************4e62
Auth Token for device ‘arduino1’ : *******************e878
But when i run the project, in my Blynk screen ,i take always the results of the ‘arduino2’ , even when I choose the device ‘arduino1’ .
What i have to change?

Are you using selector instead of one of the devices in the widget displaying results? It’s not enough only to change device in selector widget, other widgets in the app should also be set to selector, otherwise it will not switch between devices and app will be unusable. Check that, you should now have one more device in widgets, arduino1, arduino2 and selector. So just pick the last one.
