I had two Microsoft Power BI reports that I have been appending for the last six months, and now they have completely disappeared ! It seemed like it happnened between December 29th and January 2nd.
When I open Power BI, I see a blank page. I need to be able to restore these lost reports. It would take a very long time to try to recreate all the graphs I created in the last six months. This is very frustrating !
Definitely should click the smiley icon in the upper right and send a message to support with a screen shot. Probably your best, fastest route to a resolution.
