The total runtime of the Liked songs playlist no longer shows up on the windows 10 Spotify app. It is not impacting any others they all show total number of songs and the runtime at the top of the screen under the playlist title.
It is currently an expected behavior for the Liked Songs playlist not to show the total time. However, there is currently a Live Idea in the Idea Exchange of the Spotify Community for showing the total time for Liked Songs.
If this is something you’re interested in, I would recommend adding your +VOTE to this idea. The more votes an idea gets, the likelier it is that Spotify will implement it, and you can read more about how feedback on ideas reaches Spotify here.
Let me know if you have any other questions, and have a good day!
