standardoptions such as delete are not available with gmail in iOS 11

I have the latest gmail app with iOS 11. But as I swipe up and down on a email message, the standard options are not available to me so for example, I cannot delete a message. When I swipe, I hear voice over say: Toggle Star, Archive and Activate.
I have no idea what toggle star is. If anybody has figured this out,I would appreciate hearing from you.
Thank You!
