If you’ve purchased Roblox Premium on the iOS Mobile App for Roblox and it’s your first time doing so then the account you’ve gotten it on would be the original account bound to the subscription.
Say your subscription is cancelled or you’re attempting to get Roblox Premium on another account would automatically send the subscription and robux over to the account that the subscription was initially started on when you first subscribed to Roblox Premium.
This has been an issue for years and has yet to be fixed.
People are losing money due to this issue and Customer Support isn’t helping at all.
This needs to be fixed, once and for all.
