When you go to Settings > Account Settings on the Roblox website, you have the option to change your location. However, when you scroll down to “s” you are presented with a country called “Swaziland:”
And, when you scroll up to “e” there is no selection for eSwatini:
Which is surprising, as eSwatini changed their name in 2018, 2 years ago.
Either eSwatini or Eswatini would be an acceptable change.
It started happening ever since eSwatini changed their name.
Repro: Go to Settings > Account Settings and then scroll down to Location. Then scroll down and see the lack of and existence of two monikers.
