I am running Ubuntu 20.04 on lenovo thinkbook laptop. On wifi, Spotify and Netflix work perfectly (also on Chromium)
However, when connected to wired Ethernet(different source than wifi), internet works normally, except for Spotify and Netflix. It is not the problem of the wired ethernet, it works on other devices. Other possible solutions were adding required DRM modules. This also wasn't the solution, because it already works on wifi.
Any idea what should I do?
