When hovering your mouse over the Create Group button on the groups page, text appears which notifies you that you need a Premium membership in order to create a group. This is incorrect as I was successfully able to create a group without Premium following the recent update which allowed all non-Premium users to join up to 100 groups.
To reproduce this, simply hover your mouse over the Create Group button at Groups - Roblox. This bug only occurs if you do not have a Premium membership, otherwise, the text will be “Create a new group”.
The text should simply say “Create a new group” to all users.
However, this bug can be flipped two ways; there may be a chance creating groups was accidentally unlocked to non-Premium users or the text is in-fact incorrect and needs to be updated.
