ok so i have simulated around 5000 matches and i still have not gotten gems for it. I have tried all the tricks in other topics, but none of them worked. i have completed 7 levels since then, and i have spammed the speaker button countless times. Nothing works, and i need the gems at this exact level because I cant beat the oasis without new armor.
Just keep simulating. The number of simulations eventually does show up in Achievements.
