What does it mean that the mobile phone initiates a nail meeting and prompts to join?

This means that the meeting has already started. You can click to enter. Don't be late. There are many functions of nailing, such as attendance, sign-in, approval, login, announcement, nailing board, nailing email and so on. Nailing is mainly aimed at small and medium-sized enterprise users, and its feature is that it is clear whether the message has been read. Nailing shows a list of nailing events, which can be sent to friends by phone or SMS through voice or text, and attachments can be sent at the same time, and friends will receive reminders after sending them. The news must be reached, the computer, mobile phone and cloud information are synchronized, and you can communicate at any time whether you are in the office or on a business trip.
