I use QQ on my mobile phone, and a friend's avatar has become original, and the signature has not been updated, but the message I sent can still be followed. Why?
This is a network problem. Mobile phones can't compare with computers. The connection of the mobile phone is wireless and not very stable. Many people will encounter this situation when they just log in with their mobile phones. You need to click on someone's avatar to appear in the dialog box, and then you can update it later. Mine is the same. Don't worry, brother, it's normal.
