As a Roblox developer and user on the platform, it is currently impossible to join a game where your friend is playing and join it just to be on the same server as the friend.
On the platform, I always play front-page or small games that I usually find and whenever joining these games, I 100% normally would join a server my friend was or is in that particular game, this is annoying as a user when I leave and rejoin through the “Play” button always and always.
As a developer, I want to make sure I join some random server instead of my friend so I can experiment and observe what users do and some debugging for my game, and how it’s set to default, it makes it hard to not do so.
A setting inside “Account Settings” would be reasonable to put in as most settings for game and account privacy would go into there, such as Privacy or Security:
If Roblox is able to address this feature and issue on the platform, it would improve my user and development experience on the platform and on Roblox, because it would allow me as a user to not join a server with friends for private/specific reasons, having a setting for the account and to toggle it would be suitable so I wouldn’t have to join games with friends.
