Can't get K-9 Mail to show folder list display

Can't get K-9 Mail to show folder list display on my current phone. Used to display on previous phone. What settings might I change to affect this? (Want to set 1st/2nd class folders... but can't even get to the folder list to set this... )

fwiw, stopped by the K-9 Mail Google Groups forum... and Google Groups UI is almost impossible to use. Couldn't even find a new-topic button, despite all attempts to find the "enabled post via web" settings that seem to be non-existant). Very few of the google-groups buttons actually work/do anything.. from Chrome. WT... F...??

 

(Thx tcat007 for reply.)

I can't get/see/view the Menu/Folder List in the first place... that's the prob. All I see when clicking on the per-account icon is the Inbox. Then "escape" the inbox and I go back to to the account list.

On previous Android phone, when "escaping" the inbox, would then move to "all folders in IMAP account" list. But current phone/config doesn't do that.

Thoughts?

 

Solved. As per what tcat007 was prob trying to say (and thx again, tcat007): there's a "Folder List" option in the "menu." Never, ever saw that before (never needed to with previous K-9/rev behavior that auto-showed the full folder list upon "escape" from Inbox).
