Favicon from provided Logo

Hi guys

I’m using the latest nextcloud version (12.0.4) and I have a big problem with favicons.
I’m using the standard nextcloud theme, I have just changed the logo and the background color for the login page and menu bar. ok so far…

Now the problem: Nextcloude use my provided logo as favicon for the loginpage and for the config pages - ok
But now, for some pages like “Files” and “Activities”, nextcloud use the defualt icon from the menu as favicon. For example, when I am in the “Files” Menu, a folder is used as favicon.

I just want to use my logo as favicon on every page, how can I do that?

I would be very happy if somebody can help me.

Kind Regards,
Philippe
