Hello, Youyou, first of all, I suggest you try to clear the cache, change the access point, switch the extremely fast mode (Android and IOS), switch the compressed relay (Saipan and JAVA), and change the network identification (UA) to see if it can be solved. I hope I can help you! Meanwhile, I suggest you try to download the latest version 9.0 in official website, wap.uc.cn. If you still encounter problems, you can go directly to Sina Weibo: @UC Browser-Customer Service Wizard for feedback.
