number not showing on iphone 13 but does show on 12 under mobile

Hi there,

looks like the iPhone is auto converting the number to a link.
Options:

a) You can use a Hook Element to add the following code into the wp_head hook:

<meta name="format-detection" content="telephone=no">

This will tell the phone to not convert it to a link

or

b) make the phone number an actual link and then you can style that link with CSS.
