Hi, @bkatkam 


I don’t know if the credential is invalid after the upgrade. Have you tried to update the report’s credential information?


If it doesn’t solve your problem, please feel free to ask me.

Hi, @bkatkam 


Is your problem solved? Since I can’t reproduce your wrong scenario here, it’s hard for me to actually help you. And we are not sure whether there is an issue, because there are similar situations but not exactly the same. So, If you have a pro license, I suggest you open a support ticket. Support | Microsoft Power BI
