Our App include an DNS Prefetch feature which could save our app’s dns resoving time to enhance the user experience.
Recently some user’s feedbacks show that there is a bug. Some China Unicom’s 4G user can not use our app because of network connection failed. We checked our app and located the problem: the DNS Prefetch feature has some compatibility issues.
We fix compatibility issues in our new version. More and more users are using China Unicom’s 4G network. For those users’ experience, we request an Expedited review.
