Hi @Keukakid! Thanks for posting to community.
If you have more than one Pandora listener using your Google Home device, you'll want to make sure that you have a unique Google account affiliated with each user. That's because each Google account holder can only link to one Pandora account at a time.
If you create these unique profiles on your Google Home, you'll be able to access the correct Pandora account by switching the Google account affiliated with your device.
Here's some more information about how to add an additional Google account to your device.
