Clients experiencing Multiple Invalid SCA Error

The incident INC3393 is now resolved following a successful rollback of the white-label service to version 0.1.655, with no recurrence of errors and consistent successful /payments/validate responses observed. Early detection and coordinated response limited the impact to a subset of clients (~10 reported), while other client transactions continued to process successfully. As impact was partial and service has been restored to expected behaviour, the incident aligns with a P3 classification, with final client confirmations continuing as a post-resolution validation step.

Some clients experienced errors when creating payments or logging in due to issues with authentication checks. The issue was linked to a recent service change that affected how authentication requests were processed, but this has now been rolled back, and systems are stable with no repeated errors seen. We are currently confirming recovery with affected clients and continuing to monitor for any further issues.
