I installed it from Windows Store, opened a blank text document, and the styles box appears to contain white text on a white background.
I opened a blank spreadsheet, typed in something, tried to create a pivot table, and it only expanded the selection without showing the dialog box.
I restarted it and those bugs were fixed, but the Pivot Table UI is still the ugly non-interactive one found in LibreOffice (which Excel got rid of 26+ years ago).
Uninstalled.
Yeah, unfortunately this seems to combine the UI and performance issues of LibreOffice with new issues from the new front end.
It also has a basic mistake in text editor UX: the caret blinks independently of caret movement. This means that the caret is invisible half of the time while trying to navigate text. Most text editors avoid this by restarting the blink cycle to force the caret visible on each movement.
File a bug!
