hey, has FreeTube been having issues displaying playlists for you? I thought it was because I had recommended videos turned off, but turning them back on, playlist info still isn't loading for videos. Everything else is fine. (you're the only other FreeTube user I know; I did send a support email but got no response back when I thought it was recommended videos turned off.)
for me, it still worked. but maybe you can try reaching them through their github page:https://github.com/FreeTubeApp/FreeTube
