All my boosters gone!!

Same here but i’m stuck on level 6927 🤬🤬

In the case of Phone, your collected booster is stored in phone memory. This stored booster can not be synced with the server, because the game studio still does not have this process.You will not be able to transfer the boosters to another device, you will lose the complete booster for app uninstalling or crashing.

Since boosters are stored locally on device memory, we cannot guarantee that your boosters are secure.

However, Please check HERE.

Yes you're right 😢

Here are some tips for not/less facing this kind of problem in the future,

Don't open game when battery below 25%
