Nope, I just went into the Strike app, clicked on my profile in the upper right corner and then clicked on "Bill pay" under the "Banking" tab. In there, it gave me all the normal stuff you need to fill out to pay from a bank account. I went to my Honda loan and added that as a new payment method, made a payment from it, sat for a moment in disbelief that it worked, and then frantically signed into SN to brag.
