Can't login to PBI online due to currupted last dashboard

Hi,

I built a reportin PBI Desktop and published it online, based on this a created a Dashboard by adding whole pages to it and shared it.

Afterwards I changed in PBI Desktop the report (even deleted sites) and published it again.

Now I can't get in PBI online any more. It always tries to load the last dashboard, but it gets stuck on loading page showing the PBI logo and the loading dots.

Same for the 2 Users I shared it with.

I already tried with direct URLs to other dashboards but I'm not able to access PBI online at all.

Any idea how to get int again or maybe delete this dashboard otherwise?

cheers

Janek
