title: Gmail Add-ons starting to show up on iOS?
body: <p>I'm a Gmail Add-on developer with two add-os on the Gmail Add-on marketplace. I've noticed that certain Add-ons like Dropbox, Asana, and Trello, have started to show up inside the Gmail app on iOS. My two apps, however, Wordzen and GMass, are not showing up. I can't figure out why. They only show on Android. Any ideas?</p>
  
  <p>The official Gmail Add-on docs still state that Add-ons aren't supported on iOS, but clearly they are starting to work, since I'm seeing these other Add-ons from these well-known companies show up.</p>
