Following the recent release of VTrack v2.1.6, we are providing an important technical guide regarding system settings and calibration data. 1. Issue Overview Some users have reported issues with ball detection (non-recognition) or system freezing during the detection phase immediately after the v2.1.6 update. 2. Cause of the Issue Certain system updates trigger a reset of this virtual registry, causing existing calibration data to be lost. 3. Required Action If you experience any of the symptoms mentioned above, please perform a full recalibration using the Calibration Board. Once the recalibration is complete, the system will function normally. 4. Technical Improvements & Resolution We have implemented a permanent fix in this version to prevent this from recurring: This change ensures that your settings will be permanently preserved. You will NOT need to perform a manual recalibration for future version updates. We appreciate your cooperation as we transition to a more stable data management system.
