I first has TwentyTwenty theme installed and active. When this was active I had previously uploaded a favicon (it recommends 512×512) in the “Site Identity” section of the theme customisation.
Then I bought the Newspaper theme and switched that to active. I set the favicon in the Theme Panel but it’s still showing the one from the TwentyTwenty theme. I cleared all browser caches, tried incognito window, everything.
This doesn’t get used because the favicon for the TwentyTwenty theme still gets included in the blog page source *after* the one included by Newspaper theme, so my guess is browsers see it last and overwrite the one earlier in the source.
You can’t change this unless you go back to TwentyTwenty theme and change the favicon there.
Took me ages to figure this out!
