Hi,
For some reason my SVG file used for site icon has stopped working. I recently updated to new GP & GPP – not sure if that holds any relation to it.
I have tried jpg and png files with same response
Hoping you can shed some insight!
in Customizer > Site Identity can you remove the Retina Image as this is not required for SVG.
If the fields is empty then add an image to it and then remove it.
