I used to user the Chrome developertools, and then typed /one/one.app to see the Salesforce 1 view and I was able to select between different devices etc. This now doesn't work anymore, and I get the following error:

You can't access Lightning Experience

The page you're trying to access is available from the Salesforce1 mobile app only. Please try again from a supported mobile device. Need help? Ask your Salesforce admin.

Any ideas how I can fix this? Tia.

Reason for this one/one.app is reserved for lightning experience.

After Winter 16 you can't use one/one.app

If you want to use mobile version then use emulator.

You can still use one/one.app without inspect element and changing to mobile view.

1)Download chrome extensions like agent switch .

2)Change your user-agent to IPad or IPhone.

3)Enter one/one.app to find it working


Also in addition to Ratan's answer you can still use one/one.app

Just follow simple steps.

  1. right click > Inspect element .
  2. Now click on mobile icon and select any mobile.
  3. now open in one/one.app. it will work without any problem.

Here is the reference of what i suggest.

Cheers :)

  • The inspect element solution takes me to the same screen as the developer tools one. It doensn't work for me and I get the error message that I have posted in my original post.
