Same issue here! Shadowrocket UA WiFi keeps dropping for me too. I tried everything—restarting, reinstalling, nada. Then I found this forum thread suggesting to toggle airplane mode on and off before connecting. Surprisingly, it worked!
Also, make sure your Shadowrocket UA WiFi app is updated. Sometimes the devs push fixes without much notice.
