Xiaomi 15 Netflix Problem

Wait 5 sec.

Hi, i have Xiaomi 15 with HyperOS 2.0.218.0 (Android 16). DRM Info says that i have Widevine L1 certificate but Netflix doesn't see it. It says L3 so i can't watch contents in HD. I tried uninstall and reinstall but still same. Also video toolbox is disabled. My device is locked. What is the problem and how to fix it. Is there anyone also have this issue?
