SSRS 2016 report manager using m/d/y date parameter format in Chrome

I've got a 2016 SSRS server, set up with UK regional settings. When using Chrome, date parameter fields are using the US mm/dd/yyyy format instead of the expected UK dd/mm/yyyy:

Edge and IE are fine:

The date picker itself works fine, and the reports run normally in all browsers. All reports are set to use en-GB language, and this happens on all client systems I've tried it on. As far as I can tell all the server region and local settings are correct.

Any thoughts on how I can get SSRS to use the correct format in Chrome?

I'm not sure if this will work for you but Chrome uses it own language configuration.

Go to:

Settings 
  Show Advanced Settings
    Languages
      Language and Input Settings

And then select the desired language. (English UK)
