Launch last playlist at the point where I last stopped

[doesn123]

I want my playlists to always remember the position of each video and also to load the last played video when mpv is launched.
I use keepsession.lua to open the last played video.

When I add the following lines in input.conf to remember the last position in the video keepsession then fails to open the last played video in the next session.

script-message playlistmanager playlist-next
< script-message playlistmanager playlist-prev

The other option is to not use the above two lines. Everything then works as intended except when I use '< and >' (it does work when I use shift-enter) as it then won't remember the position of the video

I know you didn't write keepsession but if you could somehow help me that would be much much appreciated!!
