Using UB and can't get Custom Multisite Favicons to work on sub-sites.
Have Checked: Allow favicon defined here to override the site icon defined in Appearance > Customization
And Checked: Use this as default favicon for all sub-sites
It is working on main site front and back end.
The ico image shows in Main site Favicon and Sub-site favicons.
I even manually put a link through the browse button for the sub-site but it didn't make any difference.
Tried a bunch of different browsers - not a browser problem.
Any help would be appreciated.
