For those relying on this plugin – while we wait for an update here is some code I am using to help mitigate the issue:

If you’re using URL coupons, this first snippet will check the url for a coupon, convert it lowercase and add a banner asking the customer to enter the code manually.

This code can be added sitewide, by using a code snippet plugin like WP CODE.

<script>
    document.addEventListener('DOMContentLoaded', function () {
        const urlParams = new URLSearchParams(window.location.search);
        let couponParam = urlParams.get('wdr_coupon');

        if (couponParam) {
            couponParam = couponParam.toLowerCase(); // convert to lowercase

            const banner = document.createElement('div');
            banner.id = 'wdr-coupon-banner';
            banner.style.cssText = 'background:#f00;padding:15px;border-bottom:1px solid #ccc;text-align:center;font-size:16px;position:fixed;top:0;width:100%;z-index:99999999;color:#ffffff';
            banner.innerHTML = <br>                <span>Enter your coupon code: <span style="background:#000000; color:#ffffff; padding: 5px 10px; border-radius:5px;margin-right:5px; margin-left:5px"><strong>${couponParam}</strong></span> in the cart or checkout to apply your discount!</span><br>                <button id="dismiss-wdr-banner" style="margin-left:15px;padding:5px 10px; background:#ffffff; color: #000000">Dismiss</button><br>;

            document.body.prepend(banner);
            document.body.style.marginTop = '60px';

            document.getElementById('dismiss-wdr-banner').addEventListener('click', function () {
                banner.remove();
                document.body.style.marginTop = '0';
          
            });
        }
    });
</script>

For people entering codes manually, this second Snippet changes the coupon error message and asks the customer to enter their coupon in lowercase. It needs to be added to your functions.php file.

function coupon_error_message_change($err, $err_code, $WC_Coupon) {
switch ( $err_code ) {
case $WC_Coupon::E_WC_COUPON_NOT_EXIST:
  $err = "Error, please try entering your coupon code using all lowercase letters. Eg: 'coupon'";
}
return $err;
}

add_filter( 'woocommerce_coupon_error','coupon_error_message_change',10,3 );

Cheers.
