Thanks for reporting this issue, @querywilly. Could you share a minimal, reproducible example of your project so I can help identify what's causing the issue?

Hi @querywilly

Quick question, did this happen on Android device only or when you hit play in Unity Editor?

Thanks,
Shawn

Hi @chkuang-g and @paulinon just android device.
it is difficult to reproduce this error.
I think it happens to users with bad internet connection.
I collect this error from user devices.
if it fails, try sending again. every time succeded 1 atemps

@querywilly

Thanks for reporting this. I think this issue is different from firebase/quickstart-unity#481 since that issue only happened in the editor, e.g. desktop implementation.

I would need to do some investigation about this. At the mean time, the best thing you can do is to retry if a transaction failed due to internal exception.

Sorry for the inconvenience.
