Why can't qq delete sentences?

First, it is related to the network speed. The network speed is too slow to connect to the server and the monitor is busy.

Second, it has something to do with your browser version. It seems that this often happens in versions below 6.0. 7.0 Sometimes an error card is displayed. The newer the browser version, the better.

Third, it is related to the quality of TX's own servers, and it is also possible that users cannot operate smoothly because of poor server maintenance.
