Google knows my real IP on one stealth Android device but not the other??

[JimJim]

I'm in country A and operate 2 sets of stealth accounts in countries B and C.

Same method is used for each set: separate 24vc Fresh IP's, separate Android tablets and separate 4G mobile connections

One difference is that one tablet runs Android 8 and the other Android 9.

When I check my device activity log with Google:
- On the Android 8 tablet, Google thinks I'm in from country B (as expected).

- On the Android 9 tablet, Google knows I'm in country A (but it should think I'm in country C).

I'm concerned my real location gets leaked to Amazon/eBay/Paypal.

What is causing this leak and how can I fix it?

use webRTC extension to make sure your real IP won't leak.
