I did email you guys, but I'm having trouble understanding this "API error" explanation. What API error? How is an API error affecting whether a check clears or not. I can understand an "API error" resulting in the funds being sent to the wrong account as you explained on Reddit 8 days ago, but not preventing a check from clearing if the funds are in the proper account as you say. Please help me understand. Right now I'm very hesitant to ever use your service again.
