Hi Andy,

Apologies for the delay.

I did encounter this issue in the past several times.

Here is what I did in Photoshop.

Create a large logo, 1000px width minimum.

Flatten the image, then resize it to a small size (80px).

Doing this has solved the issue for me.

If you like I can also log into your Admin Dashboard and have a look at the SVG logo but I would recommend doing what I explained above.

Hope that helps.
