[finnandjake1010]

Please tell us some basic information before asking for help:
Model Name: Zenfone 6
Firmware Version: WW_18.0610.2101.127
Rooted or not: no
Frequency of Occurrence: when trying to play videos on amazon prime video
APP Name & APP Version (If your issue relates to the app): amazon prime video, DRM info
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
I was trying to play some videos I had downloaded when I was on android 10, but then when I updated to android 11 the videos were unplayable because of the DRM security level, I deleted and downloaded again the videos but the quality can't get very high, I used DRM info to check the security level and turns out it is L3, yes I have tried rebooting the phone but still shows me L3

I had a problem with Netflix only. I just went to "settings" of your phone. Found "apps and notifications". I picked "app info" a found Netflix. Then "storage and memory" I choosed " clear data" also " clear cache". At this moment I reinstalled NF app from Google play. Signed in again...and its Widevine L1. It worked for me yesterday.

Thanks for the tip, but it didn't work for me. I'm still on L3.

Also have this issue.
Edit: Restarted my ZenFone, checked DRM Info. Back to L1! Netflix was still stuck on L3 though.
xmajklx's instructions worked for me afterwards.
I never restarted my phone after updating to .127 (Android 11).
In short: uninstall Netflix, restart, install Netflix (or whatever app you use).
