Why can't I sign it?
The reasons and solutions for failing to submit nail signature are as follows: 1. The page shows that submitting a signature means that the teacher chooses to remind parents in the background, and the students will display the submitted homework. If the teacher does not operate the function of reminding parents, the students will not display the submitted homework. 2, the network is slow, the upload is slow, just wait patiently for the upload. 3, network problems, try to replace the stable network.

The ding message sent by the nail will inform the other party in the form of free phone call or free SMS or in-app message. No matter whether the nail APP is installed on the receiving mobile phone or not, whether the network traffic is turned on or not, you can receive Ding's message, so that the information is barrier-free.
