As for WeChat, WeChat is very stuck and often can't receive short messages.

If there is a problem with WeChat receiving messages, it may be caused by the following two reasons: 1, the network is unstable, so it is recommended to change the access point and try again; 2. There is an error in WeChat software. It is recommended to uninstall WeChat and reinstall it. Solution: Method 1: Enter the mobile phone WeChat, then find the "System Plug-in" in "Contacts" and directly open the "QQ Offline Message". Find "plug-in settings" in it, and then find the "receive QQ offline messages" option. There are two options: Enabled and Not Enabled. Select Enabled and confirm to save. Method 2: Enter the mobile phone WeChat, then enter Settings-Privacy Settings, and then "Set as Not Enabled" in the column of "Show WeChat Online on QQ" and save. In this way, when you are invisible or offline, the other party can still see the WeChat icon on your QQ avatar, but it is displayed in gray, and you can also receive WeChat offline messages at any time. Method 3: Go to WeChat and find "Address Book". After entering, find "Offline Assistant" and click "Settings".
