Same organization, same version of Zoom, different artwork for emojis

[doso]

Despite updating to the most recent version this week -- Version: 5.9.1 (2581) -- my colleague and I noticed that we have two different sets of artwork for emojis in the chat. A prime example is :ballot_box_with_check:. My colleague has the old black square with a green check mark, whereas the emoji on my system has been updated to a solid blue box with a white check mark (screenshots attached).

Any ideas why my emoji artwork has been updated and my colleague's hasn't?

Hey @doso, are you both using the latest version of your operating system? If not, suggest updating to the most recent version of the operating system, such as Windows or macOS, and let me know if that helps?

We are both using Windows 10 Enterprise Version 1909. I have a slightly older OS build (18363.1854 updated Oct. 12, 2021) than my colleague (18363.1977 updated Dec. 14, 2021), but it's my emoji artwork that changed, not theirs, so I suspect the OS builds are not the issue. We work for a large company and can't make updates to our operating systems without IT intervention.
