I never found out how to use deep links, so this also doesn’t work for me. I am checking for:
Runtime:addEventListener(“system”, onSystemEvent)
Runtime:addEventListener(“universalLinks”, universalLinksListener) => Scott’s universalLinks plugin
local launchArgs = …
I found a solution. You can enter a fallback link in the Games App event, but I find the description not really helpful. It says it uses the fallback link if the Games App is not available, but it actually opens the game with that link, or at least somehow passes it to the game. So I was able to add that link (www.abc.de/activity/start) and use Scott’s plugin to listen to that link. When I now open the game with the challenge-button in the Games app (not the normal “Play button”), I get the event from the universalLinks listener that it was opened from www.abc.de/activity/start.
