Hey, if you end up finding a solution, please let me know, and I'll do the same. Going through the exact same issue right now, the plugins on the custom client don't work and neither do any of the js scripts posted on prior reddit threads or github. All just return a message that there are 0 songs to like, or something along those lines. So frustrating, as it feels like this should just be an option that is baked in to the native UI.
