Unable to use export to PDF functionality for Power BI reports embedded in SharePoint

I have created a Power BI report and embedded it in a SharePoint web part. Initially, everything was working as expected, but I noticed that since last week I can no longer use most of the functionalities of the action bar when I embed the report to the Power BI web part in SharePoint.

However, when I open the report in the Power BI application, the action bar is working as expected and I am also able to use the export to PDF functionality of the report.

I have not made any changes to my current report in the past 2 months, and I have also noticed that this functionality is not working for the other Power BI reports either.
