I just updated to the iOS 11 beta and while the option to manually sort podcasts within stations is still there, there does not appear to actually be a way to do this. Before when you clicked edit it would have the 3 lines on the right hand side to let you manually sort stuff. Those aren't here, and there's no option I can find to actually move them. I have several podcast feeds that have multiple shows in them, and the only way to keep them organized was through stations. Did they really remove this but leave in the "manual" sort option for no reason?
