EOS_Connect_CreateUser failing on Store Review for non-UE build (clean accounts)

Hi everyone,

I’m having a massive issue with the Epic Games Store build review process regarding EOS_Connect_CreateUser. The reviewer keeps rejecting the build, claiming that this API is not being called when launching on a clean test account.

Here is the context of my project:

  1. This is a non-Unreal Engine game.
  2. The EOS_Connect_CreateUser logic is fully implemented and bound strictly to the EOS_Connect_Login failure callback under the EOS_InvalidUser error condition, exactly as stated in the documentation.
  3. During local testing with clean sandbox accounts, everything works flawlessly when the game is launched correctly.

I highly suspect the reviewer might be launching the raw .exe directly from the build files instead of installing and running it properly through the Epic pipeline, which would naturally bypass the required command-line arguments and exchange codes, causing the EOS initialization to fail.

Has anyone experienced a similar issue where the review team fails to launch a non-UE build correctly? How did you convince them or guide them to test the build properly? Any advice on how to handle this block would be greatly appreciated.

Thanks!
