Declined credit card payments

I use Acuity Scheduling, linking to Square for accepting card payments. Over the last two weeks I am repeatedly having clients’ credit/debit cards being declined due to authorisation errors. Square tells me it’s a problem with Acuity’s implementation of strong customer authentication (SCA), Acuity tells me my clients need to refer back to their banks. I am losing business over this! Does anybody else have similar issues?

Yes @FireSaltSea I am having the same problem. Very frustrating. I use Acuity scheduling, linking to square for payment and have repeatedly had clients who are on monthly subscriptions with me have cards declined. It's a headache and all around doesn't add to professionalism or credibility with my customers. I have other problems with Acuity and Squarespace supposedly being 'same' but far from the streamlined process I desire and need. My work around temporarily has been to direct bill from Square when I see a declined card in Acuity. That requires diligence in catching when it happens/

Having this exact same problem and tearing my hair out. I've sent a support request email.

Yes! I'm having the same problem and have tried the same avenues you have with the same results. Has anyone figured out what to do?
