Issues sharing content packs with groups

I am trying to set up groups and share content packs within my organisation on PowerBI.com but running into issues.

I want my workflow to be as follows:

1. Publish datasets, reports and dashboards from Power BI Desktop to My Workspace on PowerBI.com
2. Create multiple groups 
3. Create Content Pack(s) tailored for each individual group

Step 1 is fine and working however somewhere between step 2 and 3 I have an issue. I've created the groups and content packs and tried adding users in three ways to test what is working and what is not:

• Group 1; Added a group. This group has been set up in Office 365 admin center and individuals added to it. 
• Group 2; Added individua users via their Office 365 email address
• Group 3; Added the entire organisation. 

Group 3 works. If I create a content pack and share it to the entire organisation then when I go into Group 3 and click Get Content Pack my content pack is available. 

Group 1 and Group 2 do not work. If I try and Get Content Pack nothing appears other than the Content Pack that I shared with the entire organisation. 

Can someone help me understand why Entire Organisation works but the other options do not. 

Here are some screenshots of the content pack and group so you can see my settings:





Thanks.
