Aiia incident
[DE] Commerzbank AIS for Redirect-based authorization users failing last days
Resolved on July 29, 2026.
It was noted and investigated that there were some sporadic failures with Commerzbank (DE) authorization on Redirect Callback during AIS flow that could prevent payments being initiated, since 22nd July 2026. The issue was presented on a tiny portion (less than 5%) of users (those who do not have Mobile App configured). This issue has been now mitigated.
