I see that the way to set favicons on multisite is with Branding plugin, going to branding/images.
However, when I navigate there there are 26 sites on the list against 30 sites that actually exist, as seen on network/sites, so 4 sites missing. I can’t see any obvious reason why some sites are missing? For example the site that is missing is created along with 2 other sites on the same theme, domain mapping and general settings and 1 site is not showing and 2 are showing on the branding/images list.
Can you please help with this? Or is there a different way to set favicons?
