Android 13 offers a network rate limit for WiFi and xG connections via the developer options. I'm using a Xiaomi smartphone with MIUI 14 sporting Android 13. However it doesn't limit the actual speed: I've tried it setting it to 128 and 256KBps and it still downloads at the max. speed my WiFi offers.
Am I probably not alone with this problem and this is a bug or not supported by Xiaomi? Or what am I doing wrong?
