WBFex APP has been undergoing optimization and upgrading. Once problems such as login failure, crash or black screen appear when using, unload APP and log in the official website https://www.wbfex.com/zh-cn/download to re-install or scan the QR code below.
After successful installation, user needs to click “Provisioning Profiles”-trust this application in the iOS system. Android does not need this step.
If still failed to log in after re-installation, please contact WBFex official customer service and provide your mobile phone model and software version number of the device.
