The following is ready for TESTING - use AT YOUR OWN RISK. Replace these two core files with those included in the archive:

/includes/modules/pages/checkout_payment/jscript_square.php
/includes/modules/payment/square.php

No need to un-install and then re-install the module in admin, as there are no DB changes.

Will give this a test myself, as yet havent had any declines, so what will be the best way to test this & actually trigger a challenge/response from my card issuer?
Is there something in the square dashboard that will indicate a user has been issued an SCA challenge during their transaction?

Thanks so much for looking into this, square has been a lifeline to our small business with regards increasing conversions & reducing abandoned transactions as was the casewhen we only had paypal.
