We noticed that your app uses WeChat login for authentication purposes but does not include account-based features offered by that site.
In order to use WeChat for authentication, your app must include significant account-specific functionality from WeChat.
Next Steps
Please revise your app to implement your own authentication mechanism, or incorporate significant account-specific functionality from WeChat.
If your app does include additional account-specific features from WeChat, please provide us with details on where we can locate these features in your app.
