Blog app not installing/showing

Hi

I have a new install of Perch and I have tried adding the Perch Blog app. I've tried both the old and new way -

<?php
    $apps_list = array(
        'content',
        'perch_blog',
    );

but I don't even seem to see the app menu when logged into Perch. Maybe I'm not doing something simple but I'm really stuck. Please help! :)

I've been sure to log out of old sessions, run in an incognito window in Chrome but it's nowhere to be seen!

I've looked at the video https://docs.grabaperch.com/video/tutorials/swift/installing-blog/ and I seem to be doing everything right.

I need to get this resolved ASAP as have a deadline for Tuesday..

Thanks in advance for any guidance.

Graeme
