Favicons in iOS 13 Safari
I know this is a perennial topic, but I have yet to find an answer. Until a few days ago, the icon on the tabs for my site's pages displayed correctly in Safari. Now it's decided to display the Amazon "a" icon instead. I have never set the Amazon icon as my favicon, so Safari must have picked it up from when I looked at some Amazon pages on my phone. You'd think that clearing the cache would solve the problem but it doesn't. I have cleared all web history both via Safari settings and the browser itself. I have rebooted Safari and rebooted the phone. I've turned iCloud on and off for Safari. Nothing will remove the stubborn Amazon icon.
Strangely, the Home Screen and bookmark icons display correctly. It's just the little icon next to the title at the top of the tab.
The only workaround I have found would require renaming all the pages on my site or create new ones - then the correct icon usually appears. But that's intolerable.
Somehow the wrong favicon has supplanted the correct one. I could understand it if it was an old icon that I'd put in the root directory of my site, but it isn't. The problem is almost certainly with Safari as the icons display correctly with Firefox and other browsers. Anyone else had something similar and/or solved it? Help gratefully appreciated.
