App's great but sometime in December it suddenly stopped accepting payments; even though my card is up-to-date & account has sufficient funds. I've had the same payment info for years & nothing has changed; I even checked with my bank & not only did I have sufficient funds, they said you guys haven't even tried to draw from the account. Please fix; the last thing I need is a year's worth of work wiped on account of an error on your end. It's been months. Sent an email but no reply...
