Update timeline

1. investigating Sep 04, 2026, 04:22 PM UTC

   We are receiving reports that some mandates transferred from one bank to another are being cancelled with an AUDDIS-I error. The issue appears to be affecting multiple banks, with the majority of reported cases currently involving Nationwide Bank, as well as HSBC, NatWest, Barclays, and others. Our team is actively working with our banking partners to investigate the issue and identify the root cause. We are continuing to monitor the situation closely and will provide another update as soon as we have more information.

   Following our investigation with our banking partner, we identified the root cause of the issue. The payer’s bank has since implemented a fix, and the issue is now resolved. However, further investigation has revealed that the information previously shared via email with the affected merchants is no longer accurate. We will therefore contact all affected merchants again to clarify the situation, provide the correct information, and explain the next steps. We apologise for any inconvenience caused and appreciate your continued patience and understanding.

   We have contacted all affected merchants directly with further details on the failed mandates. We apologise for the disruption caused and thank you for your patience and understanding.
