I added brewblox to my iphone home screen from Safari as a PWA, but it doesn’t appear to have an icon. Any chance you can add one to the html, or tell me how I can add it?
Apple touch icons are a property set in the header: https://web.dev/codelab-apple-touch-icon/.
Should be just a few seconds work to add a link to our favicon.
FWIW, I think there’s a website that’ll take an image a spit out all the formats/code needed for all devices (android has something similar).
