The challenge requires me to block all users' access to the Salesforce1 for iOS app or the Salesforce1 for Android app. Under my connected apps i can only see "Salesforce for iOS" and this was the one I blocked. I have verified that my Salesforce1 app session has been revoked.

When I submit my challenge it gives the following error:

"It doesn't appear that you've blocked all users' access to either the Salesforce1 for iOS or Salesforce1 for Android app. Please check again."

How can I get around this error? Would the fact that my connected app is simply called "Salesforce for iOS" (missing the "1") have anything to do with it?

Trail:  Transform Your Business with Mobile
Unit: Salesforce1 Security and Compliance
Module: Monitor and Manage Salesforce1 Usage

I am unable to complete the Challenge in this module.  Either I'm doing something wrong, or there is a bug.  There are other forum posts about this issue, but no viable answers yet.  

The Challenge:
"End your current Salesforce1 session. To pass this challenge, block all users' access to the Salesforce1 for iOS app or the Salesforce1 for Android app."​

Steps that I took to complete challenge:
1. Create a new trailhead playground (for a fresh baseline)
2. Go to Connected Apps OAuth Usage (under Setup) and confirm no users connected via Salesforce1 iOS App
3. On iPhone, log in to Salesforce1 (successfully)
4. Back under Setup as an admin, refresh and confirm that 1 user connected via Salesforce1 iOS App 
5. Click "Block" next to iOS App and confirm the action, then confirm that 0 users are now connected to iOS App (so, should've killed me users session)
6. Confirm on mobile that I am kicked out of App (successful) 
7. Go back to Trailhead and click "Check Challenge"

Error:
It doesn't appear that you've blocked all users' access to either the Salesforce1 for iOS or Salesforce1 for Android app. Please check again.


Does anyone know what I am doing wrong, or is this a bug? 

Thank you 
 

Challenge says "To pass this challenge, block all users' access to the Salesforce1 for iOS app or the Salesforce1 for Android app."

"Instructions say: From Setup, enter Connected Apps in the Quick Find box, then select Connected Apps OAuth Usage.
Click Block on the row for Salesforce1 for Android or Salesforce1 for iOS.
When you’re ready to reenable access to the app, click Unblock."

Now as  instructed in some other Challenge I have installed the Salesforce1 App on my Smartphone, which is an Android and have logged in and did looking around and stayed logged.



 From Setup, I entered Connected Apps in the Quick Find box, then selected Connected Apps OAuth Usage.
I only see Salesforce1 for Android as that is the only one I am signed into and so there is no Salesforce1 for iOS.listed.
I Clicked Block on the row for Salesforce1 for Android and I am promptly kicked off of my Salesforce1 App on my Andriod phone.
The option the Salesforce1 for Android nrow are UNBLOCK and UNINSTALL

So I run the challenge before unblocking the Andriod and it fails:

Challenge Not yet complete... here's what's wrong:
It doesn't appear that you've blocked all users' access to either the Salesforce1 for iOS or Salesforce1 for Android app. Please check again.

OK why is this ??  Is the challenge expecting you to have both an active Salesforce1 for iOS to block AND an active Salesforce1 for Android to block at the same time ??  That is not possible for me to do both at the same time.

I know I blocked the Salesforce1 for Android because I was kicked out of Salesforce1 on the phone and the Salesforce1 for Android wnet from users = 1 to users = 0.
