Mobile logo not all pages

Hello,
I changed the mobile logo with

add_filter(‘avf_logo’,’av_change_logo’);
function av_change_logo($logo)
{
if(wp_is_mobile() )
{
$logo = “logo-url”;
}
return $logo;
}

But it only works on the homepage

any ideas

Edit:
it stopped working on all pages now

Edit2:
Now it works everywhere, my guess would be caching and moving the site location

Edit 3:
And it stopped working again without changing anything
