Error messages can differ. What you do, will depend on the error message you receive.  If the check image did not capture properly, you will receive an error message that you need to retake the photo. Depending on access permissions, some errors may be corrected by using the pencil edit feature.  If there is an error you don’t understand and it is not related to an error in your mobile device operation, you may call Customer Service at 844-282-7372 Monday-Friday 9am-5pm (PT).
