Thanks so much for the reply here and over on the other thread I started today.
I’m working a live staging environment and so far I’ve done my tests on Safari Mac.
I worry that I may not have filled out all the sso-related settings quite the way I need to. Especially since I’m also also having the problem I mentioned here where I need to refresh discourse to show as logged in.
Would you be willing to share exactly how you set things up? Like perhaps share a screen grab of your Admin/Settings/Login screen in Discourse and the settings screen for the wp-discourse plugin?
I made my best guess for each setting but I think I might have guessed wrong in a place or two.
