Why is the training data lost?
Please operate the product and product APP correctly, or you can re-register for a new account to use. At the same time, we will upgrade the APP version from time to time, and you will be updated when the time comes. When training, please make sure your phone is connected (connected to Wifi or open mobile data), otherwise the training data will not be saved.
If you still have questions, please email us by email@example.com
