IFRAME refused after update til January 2020 version of Power BI Report server

[invjbo]

We have some IFRAMED reports from our onprem Power BI reportserver in some inhouse developed IIS sites and in some pages in our SharePoint 2019 Onprem instance. After we upgraded our Power BI report server to January 2020 we are getting a result where it states "This Content cannot be displayed in an frame" 

Sample of our iframe source where we utilize the rs:embed=true attribute on the URL. Specific for just these purposes.

Anyone with an idea?

Note: Brackets removed and url changed

iframe src="https://xxxx.yyy.se/ReportsBI/report/Finance/KOLL/Summary?rs:embed=true&rc:Parameters=false&Date=202..." width="1200" height="1200" frameborder="0" id="reportIframe
