Same problem. Spent hours on the phone with support and hit 3 different teams that all deflected to another team. The payments team was the second team, and they eventually punted me to someone else. It's not a browser issue, if I go into the payment section of my merchant account, I can see that they're being declined by however the ACH transaction is process. It's a joke that this software cannot even process a check payment reliably. I've setup 3 accounts, all from the same bank, and the only one that works is my own personal account. So this business software will basically only process payments from me to myself, and not from my customers. Completely unreliable, and without any error messages, there's zero chance you can track this down on your own. I'm beyond frustrated with it. I'm assuming they'd rather have you run a credit card so you're paying 3% per transaction instead of 1%, and they're working to use this frustration to force you to pay triple the processing rate.
