Anyone else having trouble adding to playlists on Android?

I haven’t hit the content limit as adding to playlists works on the web, for the same song even. 

But on Android app it doesn’t add the track, just tells me “Unable to add selected tracks to the “” playlist” - like it can’t find the playlist name to add to it perhaps?

I’ve cleared the cache, logged in and out, and reinstalled the app.

Anyone else having this issue or is it my account?
