FinionPay Payments in Member Platform are degraded

[Post-mortem]
The incident occurred on 2026-02-04 between 08:07 CET and 21:00 CET and has been fully resolved.

The root cause was a defect in the MySports payments API integration with FinionPay, which prevented users from settling open debts.

During the analysis, gaps in code ownership and peer-review accountability were identified as contributing factors. These will be addressed by clarifying ownership and strengthening review requirements for payment-critical components.

In addition, monitoring for the affected services will be enhanced, and automated QA coverage will be expanded to detect similar failures earlier and prevent recurrence.
