Well... as clearly stated in previous blog post "With the new syncing solution, you must open the Excel app to receive new responses. Otherwise, they will not sync to the workbook." so my workflow to use Microsoft Power BI to retrieve form's data from the Excel Online file on predefined in Power BI service schedule is broken. To use Power Automate fix is not an option for me. So, I wrote a simple PowerShell script that periodically opens Excel Online file in browser, waits for it to update and then closes. The script opens supplied URL(s) every 6 hours just before Power BI scheduled data source update. Now I run the script from always signed-in user account on Windows Server that is always online and see my Power BI reports get automatically updated.
You can try the script on your local machine and leave it powered on or find a dedicated Windows machines for this task.
