Why don't micro-signal search users exist?

The micro-signal search can't find the user, probably because the micro-signal you entered is wrong. Check whether the micro signal you entered is correct. Micro-signals are generally letters, numbers or combinations with a length of 6-20 characters. If the input micro signal is too short or too long, or contains illegal characters, users may not be searched.

Two:

If the input micro-signal is correct, but the user still cannot be searched, it may be because the user has cancelled or deleted his WeChat account. Once the WeChat account is cancelled or deleted, users can no longer be searched through micro-signals. At this time, you can try to contact users in other ways, such as telephone, SMS or social media.

Three:

Sometimes the WeChat server will fail or be under maintenance, which will make it impossible to search for users normally. At this time, you can try again later, or try to restart your phone and WeChat. If the problem still exists, you can contact WeChat customer service for help.
