Reply To: Unsubscribe button hidden

Try to add the following code snippet to the Custom CSS area in Theme Settings to fix this issue.

.woocommerce-info .aw-unsubscribe p:last-child,
.woocommerce-message .aw-unsubscribe.confirmed p {
	margin-bottom: 0;
}

.woocommerce-info .aw-unsubscribe .button {
	display: inline-block;
	padding: 0;
	background-color: transparent;
	border: none;
}

.woocommerce-info .aw-unsubscribe .button:hover,
.woocommerce-info .aw-unsubscribe .button:focus {
	color: black;
	text-decoration: underline;
}
