I'm trying to use the WhatsApp web interface, but since a few days ago its giving me this error:
WhatsApp works with Google Chrome 36+
To use WhatsApp, update Chrome or use Mozilla Firefox, Safari,
Microsoft Edge or Opera.
I'm using "Chromium Version 70.0.3538.110 (Official Build) Built on Ubuntu , running on Ubuntu 18.04 (64-bit)"
Refreshing the page doesn't seem to work to fix it.
The linked duplicate did not help me, first, I expect Chromium 70 to be detected as Google Chrome 70, since it has all the required features, and I don't have any of the listed extensions installed from the second answer.

Workaround: Change your user agent (e.g. explained here https://winaero.com/blog/change-user-agent-chrome/) to chrome and everything works fine.
I set it to
Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.80 Safari/537.36
I also wrote them an email, will post updates:
