Application no longer available in region Australia so cannot get update

Profcorron​ Plants vs Zombies 3: Welcome to Zomburbia was an earlier version of what has since become Plants vs Zombies 3: Evolved. The game was taken offline for a major overhaul and has undergone numerous changes since then, with development and updates still ongoing.

The current version is being rolled out gradually through Early Access in selected regions. Germany was added to the list of supported regions just yesterday, October 14, and we have confirmed that more regions are planned for the future.

While there's no confirmed date for Australia specifically, it's reasonable to expect additional regions to become available as development progresses towards the planned worldwide launch.

That said, I can understand the frustration, particularly for players in Australia who previously had access to the game. Hopefully, Australia will be among the next regions added.

It was previously available. Both as evidenced on your own forum and my access in the App Store for the last few months.

It would have been nice to know in advance so I could hand over community leadership and not have wasted so much time prepping for the future. 

all the best with it. It looked like a cool update. Shame I will probably never get to play it.
