Ticwatch Pro 4G 4X Tapping shows SERVICE_DISABLED

I just bought this Ticwatch Pro 4G, Chinese version, then I followed the instruction to scan the QR code, but I didn’t show any, instead threw a toast saying “SERVICE_DISABLED”.
I’ve searched the forum, basically, it might be something wrong with Google services. I’ve updated gms to the latest version and confirmed services are up and running.
But still no luck.
I’ve captured some logs from logcat and found something interesting:

06-07 15:12:28.438 2054 2054 E FirebaseQRCodeActivity: Could not get Firebase token. Exception: java.io.IOException: SERVICE_DISABLED
06-07 15:12:28.438 2054 2054 E FirebaseQRCodeActivity: java.io.IOException: SERVICE_DISABLED

06-07 15:12:28.438 2054 2054 E FirebaseQRCodeActivity: at java.lang.Thread.run(Thread.java:764)

So it seems something wrong with the Firebase token
I’ve tried everything I could, but still not getting QR.
But Watchmakers works just fine, I don’t know if they’re also using Firebase.
I think I need help on this, or is there any other way to get QR correctly?
If this problem not getting fixed, I think I’m gonna stick with Watchmakers. Just bought their premium membership.
But to be honest, Facer got much better faces.

@Facer_Official, maybe you could help? Have you tried contacting facer-support@little-labs.com?

Hi!

Sorry about that - can you let me know what type of phone you are using with your watch?

iPhone X 256GB with framework 12.3.1

Thanks! Syncing faces from iPhone relies on a Google service which is unfortunately banned in China. We’re going to look into alternative solutions for that market to enable the service broadly.
