We warmly welcome you to the Friendly King Community's Candy Crush Saga forum.😊
In the case of Android and I-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 and the boosters are not refundable.😭
Perhaps your boosters were destroyed due to a Crushing in your game app.
