New updates are added at the bottom of this story â¦â¦.
The original story (published January 19, 2021) follows:
Several users who have recently reset or purchased a brand new Wear OS device are now virtually unable to use it. This is due to a new bug that has emerged regarding adding or copying Google accounts.
According to reports, copying Google accounts from the phone to a Wear OS smartwatch does not yield any results as it returns errors such as “We could not copy your accounts” or “Error 400”.
I have tried several ways to connect my google account to my OPPO WATCH so that I can use the extra features and it will show on a blank screen after entering my password or reading a 400 msg error.

I just bought a new Suunto 7. I have set it up a few times now, but still cannot get my google accounts from my phone, the smartwatch. The WearOS app runs in a blank page or displays error 400 or just indicates that the account was not added. I have reset my watch several times. I cleared the bluetooth information on my phone and cleared the cache of portable devices from Google services.

The above does not always happen, as the process can also cause the Wear OS app to turn into a blank white screen without returning an error message.
Moreover, the problem is not limited to a single model of smartwatch, as complaints are coming from users of Suunto, Fossil, Casio, Ticwatch, Huawei, Oppo and probably others as well.
In addition, there is currently no official recognition from Google on this subject. This is only plausible, however, as the first reports of the problem only started coming in about five days ago.

It is also worth mentioning here that several users reported that the problem was gone for themselves on their own, after which they were able to log in without any issues.
If you’re not one of those lucky users, don’t worry, as several complainers have been able to work around the issue by simply disabling two-factor authentication. You are also free to try.
But if that doesn’t suit you, you can also try wiping data from Wear OS, Google, and Google Play Services apps.
Again, it’s quite possible that Google has already silently solved the problem. The fact that several recent comments said the problem had magically disappeared for them is testament to this.
However, this is not clear at the moment as there is still no official word from Google.
That being said, we will continue to monitor the matter and update this article as the situation evolves.
