Graphical issue with PBI Online

Hello,

Yesterday evening, my dashboards started to display graphical errors like:

• charts with black lines in the background of the chart, which disappear when you click another chart (clicking, not selecting!)
  

   

• in the matrix, some fields row headers are blank

   

  

   

• same for the slicer, showing blank and empty

• and other graphical error where the symbol is showing full black

I opened the report with PBI Desktop and it was working fine. I tried to reupload it online, but it did not change.

Is anyone else experiencing the same issue?

FYI, I have been using PBI for months, this is a first time ever!

regards
