I have installed LineageOs 20.0 (Android 13) with MicroG.
Some apps a a bit picky in security like Netflix. To fix this use Magisk.
Download latest version of Magisk. 25.2 at this moment.
If Magisk is installed and working well, go to settings and enable ZyGisk and hide Magisk.
Install F-droid, if it is not installed.
find the package: Fox’s Magisk Module Manager
Use this to find these modules:
liboemcrypt disabler (specially for Netflix);
MagiskHide Props Config;
Shamiko;
Universal SafetyNet Fix.
You might have to use MagiskHide Props to select a ’ better’ fingerprint (see).
Then in Magisk again: Go to settings (do ‘not’ enforce Denylist), but Configure Denylist.
Find Netflix and all other apps that are ‘misbehaving’ 
Everything is working well here. Netflix too. Even with an open Bootloader.
