I use the free account of power bi. So in march I upload and pbix file and publish on web.

Until then I had not login again on app.powerbi.com, but I know The password (and save it on Chrome).

Well..... When I try tô login today, the app.powerbi.com always says password was Wrong.

Then I go tô register again and create a New password, but all dashboards and data disapear :(

How can I recover that?
