Why is my UDP sandbox login still popping up?

Questions & Answers
1

I am using IAP with UDP. My initial UDP login that I put in my opening script (suggested to be put in GameManager script),

StoreService.Initialize(listener);

I commented out. But when I go to my IAP screen, the login pops up.
There must be some Store Service Initializer not in my scripts.

I had two people play my game downloaded from the google play store and both had this pop up on them.

How do I get the login to not pop up?

So, it turns out if you are publishing your app to the google play store, you can’t use UDP. The IAP store setting has three options. Having UDP selected still played ads in google play store, but the UDP sandbox login pops up.
