Logo not appearing when scroll down

The image it wants does not exist - which is fine but how are we supposed to upload it?

Hi there,

Any chance you can link us to your site?

Thanks, we figured it out. We had to select the new logo in Customize > Layout > Primary Navigation > Navigation Logo.

We figured if we updated it in Site Identity, it would carry through but it didn't

If you are using GP Premium 1.8 then updating the logo in site identity should work.

The navigation option no longer exists in GPP 1.8.

You can use the use navigation as a header option:

And sticky navigation logo option if you need one:

Hope this helps :)
