Changing the Chrome on iOS User Agent for Request Desktop Sitehttps://blog.chromium.org
Chrome on iOS sends two different User-Agent strings, depending on the version of the site being requested by the user.
In M84 and earlier, the User-Agent string sent when the Request Desktop Site option was selected matched the string used by Safari Desktop. Starting with M85, the User-Agent string sent with the Request Desktop Site option changes to include the CriOS/<MajorVersion> tag.
The goal of this change is to allow developers to tailor the user experiences to account for differences between Chrome and Safari on iOS. This change adds more information to the Desktop User-Agent string, but including the browser name and major version in the User Agent header is still in line with the goals of Chrome’s User Agent information reduction plans.
