Play Console Error Fixed – Play billing library version 6.0.0 or higher – Unreal Engine 5.3

IMPORTANT:

BEFORE MAKING ANY CHANGES, MAKE A BACKUP OF THE ORIGINAL FILES

JUST SHOWING WHAT WORKED FOR ME

1) Visit https://drive.google.com/file/d/17JXGPI30zESHl15NAj5-5-agHIp-QdHg/view.

2) Download the zip file containing 3 folders.

3)Go to:

C:\Program Files\Epic Games\UE_5.3\Engine\Plugins\Online

4) Make backup of 3 folders: Android, OnlineSubsystem and OnlineSubsystemUtils.

5) Extract the zip file downloaded earlier and replace the 3 folders at C:\Program Files\Epic Games\UE_5.3\Engine\Plugins\Online.

6) Now go to:

C:\Program Files\Epic Games\UE_5.3\Engine\Plugins\Online\Android\OnlineSubsystemGooglePlay\Source

7) Open file ‘OnlineSubsystemGooglePlay_UPL’ with notepad.

8) Find this line:

implementation ‘com.android.billingclient:billing:4.0.0’

and replace 4.0.0 or whatever number there is with 6.0.1

so it will look like:

implementation ‘com.android.billingclient:billing:6.0.1’

9) Save the file.

10) Now restart the Unreal Engine and package the project.
