Why can't I download the iOS 11 public beta?

iOS 11 Beta

If you're already a member of the Apple Beta Software Program but have not received the first iOS 11 public beta you may have to re-enroll your device.

First navigate to Settings > General > Software Update to check if you have the iOS 11 public beta. If you see a message that reads "Your software is up to date" then you need to re-enroll in the Beta Program. Make sure you have upgraded to iOS 10.3.3 then follow these steps:

  1. Navigate to beta.apple.com/profile on the device you want to update.
  2. Sign in using your Apple ID.
  3. Download the configuration profile to your device.
  4. Restart your device.
  5. Navigate to Settings > General > Software Update and install iOS 11.
