Olympiadry

Hello, I searched a lot but I didn't find any answer... I'm a new player (1month +-) and I'm currently in Jotho. I used to have a team share exp and I actually like it. But some days ago, when I connected, I lost the team exp share. And I don't know if it's possible to find it back and how... Thank you already! (I'm talking about the way to earn exp in the game and NOT the item exp share) Have a good day :)
