I'm so confused. I'm developing some Word Add-Ins to publish through Appsource, but I am not sure if I should be using the Fresh icon style (2018) or Monoline (2019) ? Can anyone point me at a definitive reference (or confirm if the second URL below is definitive?) or do you know? Thanks in advance.
