Transport will not stop at end marker

It seems that it should be a simple fix, but I can’t figure it out. Playback continues past end marker. There is an old post regarding this problem but it refers to an “options” menu that I can’t find. Options → Misc Options → Stop transport at session end. Can someone help me find out what is going on? Thank you.

Preferences > Transport > Stop at the end of the session

is off by default, have you enabled it?
Also note that this only applies to playback (not recording).

Thank you Robin for your help. Much appreciated!
