Hello,

The custom color should work on all devices, so I can't say what the issue is without taking a look. Can you please provide me the URL to the booking form?

You can use this CSS rule on the page between style tags where you will overwrite font from our plugin.

<style>
.amelia-app-booking input[type="text"], .am-modal.am-in-body input[type="text"], .amelia-app-booking input[type="email"], .am-modal.am-in-body input[type="email"], .amelia-app-booking input[type="tel"], .am-modal.am-in-body input[type="tel"], .amelia-app-booking input[type="url"], .am-modal.am-in-body input[type="url"], .amelia-app-booking textarea, .am-modal.am-in-body textarea, .amelia-app-booking select, .am-modal.am-in-body select, .amelia-app-booking .form-control, .am-modal.am-in-body .form-control, .amelia-app-booking .am-stripe-card, .am-modal.am-in-body .am-stripe-card,
.amelia-app-booking h1, .am-modal.am-in-body h1, .amelia-app-booking h2, .am-modal.am-in-body h2, .amelia-app-booking h3, .am-modal.am-in-body h3, .amelia-app-booking h4, .am-modal.am-in-body h4, .amelia-app-booking p, .am-modal.am-in-body p, .amelia-app-booking span, .am-modal.am-in-body span, .amelia-app-booking div, .am-modal.am-in-body div, .amelia-app-booking section, .am-modal.am-in-body section, .amelia-app-booking ul, .am-modal.am-in-body ul, .amelia-app-booking li, .am-modal.am-in-body li, .amelia-app-booking a, .am-modal.am-in-body a {font-family:fantasy !important;}
</style>

We insert font fantasy just for example, but you will replace font that you need.

Hello Hamdi,

There is a separate parameter as well in the script
