ArcGIS Login

Good day,
  I have a come across an annoying defect(?) regarding using the ArcGIS for PowerBI tool.  When I want to create a map, I use my ESRI Enterprise credentials to login and have no issues creating the map using my content from ESRI.  Let's say I create the map and then save my Power BI report.  A few days later I want to go back into Power BI and update the map with some different data.  When I go to update the map, it tells me that I am not logged into ESRI.  What's annoying is that it doesn't give me an opportunity to login anywhere.  Where can I log in to ESRI in an existing map?  My only work around I found is to create a new map, where it does give me the opportunity to login to ESRI and then recreate the whole map again.  I find this very annoying and there must be a better way to way to do this.  I feel like I must be missing something here - this would be a very obvious miss if there isn't a way to log in to ESRI in an existing map.  Any help on this would be greatly appreciated!
