Duty Finder notification fails, no support for paying customers – Guildwork Review

I subscribed to the Guildwork service and downloaded the app for the sole purpose of using the remote notification and confirmation of Duty Finder queue pops within FFXIV, but that feature does not work. Other notifications and chat work, but the only feature that matters does not. The support link on the Guildwork website directs to a zendesk support page that is closed.
