MOOER iAMP

After updating all of our iPhones to iOS 26.5.1, the MOOER iAMP app stopped working correctly. The app connects to the F15i amplifier via Bluetooth, but constantly displays the message: “The current app version is too low, please upgrade it to the latest version,” even though version 1.6.0 is the latest version available on the App Store. I have tested this on multiple iPhone 17 devices in my household with the exact same results. Reinstalling the app, restarting the phones, switching between Wi-Fi and cellular data, and reconnecting the amplifier did not resolve the issue. Additionally, the login screen is locked to the +86 country code and does not allow users from other regions to select their country. The amplifier itself works, but many of the app’s smart features have become unusable. Please address this compatibility issue with iOS 26.5.1 as soon as possible. This is an excellent product being let down by software support.
