The app frequently displays the wrong gear. Example: the motorcycle is physically in Gear 3, but the app still shows Gear 2. This issue did not occur previously and started recently, indicating a regression bug. RPM and speed readings remain stable, so this is not user error. Incorrect gear detection affects data logging accuracy and makes tuning analysis unreliable. I have contacted the developer via email but received no response. Please fix the gear inference algorithm or provide manual gear ratio calibration. ### 3/5 — b link issue *2025-07-29, version 2.7.1* Sometimes can connect somtimes cannot, i even replace with a new b link and after awhile it became the same issue... ### 2/5 — I have already paid the app *2025-05-17, version 2.7.1* Its says i need to purhcase the app again ### 2/5 — Lỗi đã thanh toán 1 lần nhưng vẫn bị yêu cầu thanh toán *2025-02-12, version 2.7.1* Tôi đã mua app 249.000vnd nhưng sử dụng 1 thời gian lại bị bắt mua lại.
