Why do I set up qq space to talk about unsynchronized personality signatures but still synchronize?

First, we should set up two places. QQ client and space should be set up.

Second: use the latest secure browser, advanced version, relatively complete plug-ins, etc. To prevent invalid settings;

Third: remember to save after setting;

Fourth: if it can't be solved, try to do the same operation on at least 2 QQ numbers on 2 mobile phones and 2 computers;

To sum up, this problem can be completely solved!
