Outdated documentation = i’m stuck

The documentation does not match the current UI. After step 3, I get:
“Looks like you’ve got an old link, or have mistyped something.”

Other parts of the documentation look like they are for an older version of the app. I’ve been trying this for a while and it’s probably the most difficult-to-use plugin I remember on WordPress.

Additionally, it looks like the integration for WordPress is no longer an option with Onesignal. If this is the case, they should remove the plugin from WordPress.
