AYANEO released a customer service update asking any buyers who experienced unresolved after-sales support issues with the company to reach out to them. This appears to have no expiration date, as they are explicitly asking for issues that happened before 2025.

The update was quietly released on their AYANEO Next IGG page, a device that was released in 2021. https://www.indiegogo.com/en/projects/ayaneo/ayaneo-next-future-windows-handheld-for-aaa-games/updates/28
