Hi @rodolfoq ,
This is Theodore from PageFly - Shopify Page Builder App.

Your iPhone Safari might not show the favicon update for a few reasons. Try:

• Clear Safari cache and website data.
• Force-quit Safari.
• Check favicon code and file location.
• Use a different browser to see if it's a Safari issue.
