[Podurama app] Playlists suddenly being limited to maximum 10 episodes?

I have been using the Podurama app for about six months now and I generally loved it. But a couple of days ago I tried to add an episode to my "Listen Later" playlist and was told playlists could only have 10 eps on the free version. This didn't use to be a Premium-only feature (as I have about 50 eps on this playlist). It's kinda shaddy behavior to take an existing free feature and then move it behind a paywall, especially without a warning. Makes me consider that I shouldn't stay with Podurama, as much as I love the app otherwise.
