If Stobox's campaign changes to the distribution of its tokens to Probit Exchange, there will usually be a notification in the bounty group, as in the Bounty Detective Telegram.
For whatever reason, if you don't see the notification, maybe you forgot to open the Telegram channel message from the STOBOX bounty.
My Student Coin did not participate in the campaign because when it happened the Student Coin was in progress following the MYID campaign from the Irfanpak10 Manager.
