Starting in either Edge 119 or 120, it seems that Pandora won't start playing automatically when the site loads. I did find the support article saying that eventually, Edge will learn your preference on this. I also added "www.pandora.com" to the allow list of Media Autoplay in Edge's settings but that hasn't proven to change anything yet. Additionally, playback keeps stopping after each song finishes requiring me to manually click the play button again. The browser console shows "Uncaught (in promise) DOMException: play() can only be initiated by a user gesture." I see in WakeLock.jsx that there is some hacky workaround that is meant to keep the browser from "going into sleep mode". There is also mention in a comment about how a user gesture is required but it doesn't seem that the code is working any longer in Edge.
