WhatsApp works with Google Chrome 36+

whatsapp

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.

enter image description here

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:

Dear WhatsApp-Support Team,

for many months, probably years the web-app was not only supported for chrome but also for it's step brother chromium. Technically they are interchangeable, both support the same features and standards. But since about a week ago the app stopped working on chromium. It doesn't seem to be a problem of a missing feature as spoofing the user agent allows me to still use the app. It's just kinda hacky and I'd prefer it to work native (again).

Season's greetings
