Invalid Lost widevine L1 again after renewal on Mi 9 after some time

[mar_robHD]

Today, 10 hours ago I got a new L1 certificate on my Mi9 via fingerprint payments. Unfortunately the widevine status changed from L1 back to L3. I'm also unable to download a new certificate. When trying to download the new certificate, the error code 1 pops up

Download to your PC:

https://dl.google.com/android/repository/platform-tools_r31.0.2-windows.zip

Connect your device, extract that ZIP, open the command prompt, browse to the platform-tools folder and enter:

adb logcat > log.txt

You must have installed something that broke the Widevine on a deep level. Some Magisk module perhaps, or flashed some ZIP.

The important part is here:

I rebooted and it's now working somehow. I did the same hours ago. Thanks
