Mobile Suica issued a system notice today: there is a new version of Suica App (v2.7) on the App Store, users must update by July 21. After that date you must use version 2.7 to access Mobile Suica services. The only difference I could see is that Mobile Suica Shinkansen eTicket purchase history search has been added going back to July 2019. Mobile Suica Shinkansen eTicket service ended March 13, replaced by the cloud based Ekinet eTicket service.
Some users have been experiencing multiple Mobile Suica 1201 recharge errors recently. There’s a lot of cloud work JR East has to do on the Mobile Suica and Ekinet systems in preparation for the next generation Suica debut in spring 2021. The mandatory update requirement is a sign something is changing on the backend. Hopefully JR East is fixing all things Mobile Suica.
