Hi i am having this horrendous issue as well. This is completely damaging my business. More than 5 new clients making payments of $250 or more are not being recorded. Thus, I am losing thousands of dollars due to this pathetic issue. I am considering suing because how worthless is squarespace to charge us to have an online store monthly and fail to process monthly payments?? Jason, if you find any way to fix this please reach out to me so we can figure this issue out together. I sent you a private message with my number.
