Queuing occurs when checking duplicate because too many people use the duplicate checking system. Due to the limited detection ability of the duplicate checking system, only a certain number of papers can be detected at the same time. If the number exceeds this, you need to queue up.

PaperPP will also have this queuing phenomenon during the peak period of duplicate checking, which is also to ensure the accuracy of duplicate checking results and be responsible for everyone's papers. Please be patient when you meet the queue when checking the duplicate. Don't cancel frequently, and submit frequently, which is equivalent to queuing again, which will delay more time.
