How to update iOS11 Beta I have already installad iOS11 Beta 1 with Apple Beta Software Program.

But there are new beta releases (Beta 2 and Beta 3), when I navigate to settings-general-software update, it says, 


  iOS 11.0 Your software is up to date


I have also checked version, it's 11.0 (15A5278f) which is actually Beta 1.

Why don't new updates appear in software update section? How can I install new beta versions?
I had the same problem.

On your phone log onto beta.apple.com with the AppleID you used to sign up for the public beta.

There should be a link, once you log on, to tap on to download the correct profile that will then kick off the next available IOS Beta release.
