How do I change an app form from portrait to landscape?

Thank you for reaching out. 

You can check the landscape view of your app in the preview option in the builder, or you can forward it to try on your device.

I hope this can be helpful.

If I misunderstood what you need, or you have questions, please let me know.

Oh Dang.... I should have known that....

Thank you !
