Google Assistant not connected (WH-1000XM2)

[athorod]

- I just downloaded and installed the 2.0.1 update for the WH-1000XM2 to be able to use Google Assistant.

- I opened the headphones app and changed the use of the NC-button to "Google Assistant".

- When I press the button I get the message "Google Assistant not connected" in the headphones.

I have tried every thing I can think of to make it work, but to no avail. I cannot find the headphones in the google assistant/home app either. 

I am located in Norway but I can use Google Assistant with my Google Home device as long as I have English as the default language (which I have). 

My phone is a Samsung Galaxy Note 8.

Does anyone have any suggestions to make it work?

One more very important detail. I wasted hours to turn on the Google Assistant (on XM3 and then on XM4), but didn't succeed. The problem was that my device's language was not English, but Russian (Ukraine). I changed the device's language to English reboot it and everything works.

By the way, Google Assistant understands me in both language anyway.
