PowerBI report not loading in Sharepoint?

Hi All,

I have a PowerBI Report integrated in Sharepoint site. Following are the steps followed

Steps followed:

1. PowerBI Report was created and Roles were created with filters

2. Report published on PowerBI service

3. Users were assigned to Roles

4. Embedded URL of report was integrated in sharepoint (URL was linked to iframe in sharepoint)

Behaviour:

1. User logs in Sharepoint , PowerBI Report is not visible , msg appeared "This content is not available"

2. User logs in PowerBi Service in different tab

3. User refreshes page in Step 1 , report loads now.

The issue is users are not able to see the report unless they have logged in PowerBi service once. We have tested this for 4-5 users and functionality seems to be same. We don't want to request users to login in powerbi service separately. Has anyone faced this issue before? Any advice or help ?
