Hello @Mimidawn1
Thanks for reaching out here in the Community!
Moving to Guest Mode allows the guest to sign in with their own Roku account. When they do this, they will no longer have any apps on the device, but the device will be set up with the apps that are linked to the guest's Roku account.
For more information about Guest Mode functionality, visit our Support page here: Let visitors sign into your Roku with Guest Mode
I hope this helps.
Regards,
Karla
