Unable to see steam overlay in a shipping build. It worked once but all shipping builds since do not display the steam overlay

In order to see the steam overlay in a shipping build, I created a text file “steam_appid.txt” with 480 as dev testing id.
It worked great and I was able to see the steam overlay and player’s steam name.
However, it only worked with the first shipping build.

Newer shipping builds with the same steps of creating the steam_appid.txt file don’t work.
Does anyone know why this is and how to fix it?
Why would the overlay only work in the first shipping build but no following builds?
Any help would be greatly appreciated, thanks.
