I just noticed that disabling the tracking on all of my Matomo installations is not working anymore when using the current version of the Chrome Browser (80.0.3987.87) in macOS.
I noticed the warning about a cookie with the setting SameSite=None and the missing Secure parameter. I read #14395, I added _paq.push(["setSecureCookie", true]) to the JavaScript. That affects only the _pk_id, _pk_ses and MATOMO_SESSID cookies, the piwik_ignore cookie is seemingly not affected and gets blocked.
I then checked if this also happens when using the Chrome browser in Windows. It does not! Running Windows 10 and also the latest build disabling the tracking works just fine.

Can anyone confirm this and / or maybe has an idea for a solution?

Thanks
