I’m a foreigner in Shanghai using Shadowrocket on my iPhone to reach services that don’t load normally on my connection. The profile says it’s connected and a couple of websites open, but a messaging app and a video service still time out. I’ve switched between apartment Wi-Fi and mobile data and restarted the app, but the results are inconsistent. I’m unsure whether to look at the server, routing rules, or the apps themselves, and I don’t want to change settings blindly. For anyone using Shadowrocket in China recently, in 2026, what would you check first when only some apps fail?
