I started Business Central demo, try to open Power BI report inside Business Cental and saw error message:
"You do not have a Power BI account. If you have just activated a license, it might take several minutes for the changes to be effective in Power BI."
I already loged in power bi in another tab, I restarted business central, restarted enviroment, closed whole window. And of course I wait more than hour. Any other idea please? Thanks!
