Build custom email security reporting with Microsoft Defender for Office 365 and PowerBI

This looks very good. Thank you. Unfortunately, I can't get it to work for more than 4 hours. This is very frustrating. Power BI was new to me, I am only an M365 admin. This seems like Excel on steroids to me, doesn't it? I followed the instructions here and on Github to load the template and log in to the tenant. I should have the necessary permissions because I can create and run Advanced Hunting Queries. This is only a small tenant (Datacenter: Europe North). Max. 2000 mails in total in the system and max. 200 mails in the spam folder. But for more than two hours I see only 'Refresh. Waiting for other queries...'. No idea what the queries look like in the background. I can't get past the 'Refresh welcome screen' after all. Since I find the concept furiously interesting, I'll take another look at the project in a few months.
