"Preview App as" does not work everywhere

[Scott_Nesbitt]

In my preview screen I enter this and press Apply:

When I run the app, it does use the foo@ironmountain.com email to show limited rows, but it does NOT use this in the automation area, or in the generated PDF area. In my doc, I have a test:

USEREMAIL() <<USEREMAIL()>>

In the PDF, it shows:

Is this a bug, or am I using this wrong?

Thanks,

Scott
