Delete Netflix Data and uninstall Updates, then install Netflix-6.26.1_build_15_31696.apk from apkpure or so. Check your ID in Netflix and try Test patterns. If it is o.k then update with com.netflix.mediaclient_7.120.0_build_7_35589-35589.apk. This is the last working version with HD for me.mind is version below, although Google Play store showing certified, DRM Info showing L1, but NetFlix still L3, anyone know a working L1 firmware version and Netflix App version, Thanks
