ASN Bank blocks Wero payments on GrapheneOS after reported Play Integrity check

Summary
ASN Bank customers report that app version 1.36.3 blocks Wero payments on uncertified Android phones after a Play Integrity check. The policy’s origin remains unclear, and users say the iDEAL | Wero checkout still mostly works.
Key points
- Customers reported the block after ASN Bank app version 1.36.3 arrived on October 16; the app still opens and displays accounts, but some Wero payments fail.
- A user who examined the app reported finding a Google Play Integrity request in its Wero payment handling; affected GrapheneOS users also saw an API notice before the error.
- ASN support said GrapheneOS is not supported for Wero and cited Wero security requirements. EPI said it focuses on widely used platforms, but did not clarify whether Play Integrity is mandatory for banks.
- Users report that the combined iDEAL | Wero checkout mostly still works, while payments processed entirely through Wero fail on affected devices.
- Users also report Wero working on GrapheneOS in Triodos, bunq, and N26 apps; these reports do not establish that the behavior will persist.
- The Dutch Payments Association says banks connected to Wero in October 2026 and the transition from iDEAL is expected to finish by December 31, 2027.
