First of all, network problems may be one of the reasons why WeChat personalized signature does not display the home page. If the connection of WeChat server is abnormal, the signature may not be displayed normally. Secondly, the account number problem may also be one of the reasons. If the WeChat account is blocked or stolen, the signature may not be displayed. Finally, the WeChat version problem may also cause the signature not to be displayed. If the WeChat version is updated, there may be compatibility problems, resulting in the signature not being displayed normally. Considering these reasons, we can try to reconnect to the network, check the account status, or update the WeChat version to solve the problem that personalized signatures do not display the home page.
