The 69-yard WeChat can't be scanned.

I want to ask why the 69-yard WeChat can't be scanned. The 69-yard WeChat cannot be scanned because:

1, the bound peripherals have requirements for the system version. If the required version is higher than the mobile phone system version, it will become unresponsive after scanning the QR code.

2. There is something wrong with the WeChat installation package itself.

3. The network is too bad to scan successfully.

4, 69 code error, WeChat can not identify.
