I had set up a separate account sub-account under my checking account that was labeled specifically for SOLAR payments (to make tracking payments easier). However, EVEN THOUGH I CAREFULLY made sure to include it's unique 2 digit suffix this system (my bank included???) failed to recognize that it should have come out of a SEPARATE sub account. SO....YOUR payments were delayed for nearly 2 weeks until my human mind caught the error, and figured out why. (Because it had tried to draw out of the main under-funded "Checking" account rather than the SUB account that had plenty of funds) PLEASE consider making some kind of ALERTING note to alert customers that issue and/ or PREFERABLY make your system capable of more finely focused attention to the NUMBER indicated as the "pot to choose from"...rather than just the overriding main account such as "Checking". . Thank you for your consideration
