The bug
In the Help menu, the word 'support' is not capitalized in the Mojang support on Twitter link. The name of the Twitter account is Mojang Support.
This may be as designed, but I am not quite sure.
How to reproduce
Open the Minecraft Launcher
Click on your profile name on the top left corner of the screen
Click
Helpin the dropdown menu that is shownFind the link
Mojang support on Twitter
❌ Notice how 'support' is not capitalized, which is inconsistent with the name of the Twitter account
Capitalized and working! You'll see it in our next update. Cheers Mark.
