You know how the sidebars labeled ACC Buddies/Staff/WiFi all have little yellow minus sign icons next to them and that clicking on the icons will minimize and hide everything under it?

I minimized my ACC Wifi list and now I can't figure out to maximize it again.

Clicking where the icon takes me to the friend codes page, which itself doesn't seem to have any options for uncollapsing the sidebar. What do I do?

Are you clicking on the text that says "ACC WiFi" or the rectangle icon to the right of it? The latter seems to be working for me.

I don't see a rectangle icon.

Did you accidentally delete all of the friend codes you had entered? There should be an icon to the right of the "ACC WiFi" text that you can click to maximise the section.

Ok, I found it. Only now on mobile am I seeing it for some reason. Thanks for your help.
