Site favicon not showing up in Simple Analytics

Anyone have this issue before or know of any guidance on site favicons? I assume that’s where Simple Analytics pulls from to display your site logo?

I’ve tried .svg and a few .pngs. I would rather not use .ico as they are super tiny and look pretty bad. The other two sites in my list are showing up fine in your system.

Issue:

Current favicon for aghost.guru:


A site that’s working is using a .webp:
followayfinder dot com /img/wayfinder-owl-round-900-percent-1024x1024.webp

Another site that works is using .webp:
tasha dot page /content/images/size/w256h256/2024/05/tasha-page-avatar-1.webp

2 link limit on posts here, so I spelled out the domain and urn as a workaround for the previous two.

Is png off limits? Is there a size limit (pixels or disk size)?
