Hi Sara,

Thanks for bringing this to our attention.

Regarding accuracy drop, we had an internal discussion with our team this morning. We diug out the root of this issue and found that a worker was responsible for creating all these problems. We have already removed this worker from the production line.

Moving forward, we’ll closely monitor and review results on a daily basis and send you the weekly review of the processed inputs.

We really appreciate your help and patience regarding this accuracy issue and truly apologize for the inconvenience caused.

Regards,
