After installing the widevine-installer patch, Chromium can play Spotify without any issues (Firefox is also fixed). However, the Chromium installed through Flatpak (flatpak install flathub org.chromium.Chromium) still has problems. Could it be that this patch didn't consider this version? As for why I have to use the Flatpak version, it's because this Chromium version can resolve Google sync issues by using flatpak override --user --env.

Flatpak Chromium is isolated in the sense that it has its own libraries and doesn't use system libs. This patch adds Widevine to the system libraries and has no effect on Flatpak.
