Different Google Play Games user id on android and iOS

Question

I found weird problem. Google Play Games return different user id on different platforms on some gmail accounts.

Android: g004520354...
iOS: 108586408195...

I have gmail account where is user id the same on both platforms, but we found account (1 month old) with different ids.

Have somebody the same experience?

According to this documentation , that you will have a different client ID for different platform. And according to Creating multiple client IDs , if you are creating a game that runs on multiple platforms, you will need to create a separate client ID for each platform (Web, Android, and iOS). To do this, click the Link another app button on the Linked apps page and repeat the steps starting from the Create a linked application section.
