## Updates from Marqeta
### 2026-10-14 09:20 UTC: investigating
Marqeta engineers have identified an issue where 3DS authentication requests are missing the user token field across a subset of customer programs. While frictionless authentications are succeeding, authentications requiring a challenge may fail. We are actively investigating the root cause and will provide another update as soon as more information becomes available.

### 2026-10-14 10:24 UTC: resolved
Marqeta engineers identified the root cause as a recent change, which has since been reverted. All 3DS authentication flows are operating normally with no further impact.
