Hi @lele89 and welcome to our adorable Community 😊 Thanks for tagging me @Spinnifix If I understand well, your boosters are locked, is that right? If so, please follow the steps on the link below to unlock them.
There are a lot of technical problems at the
moment, but I know that this is already being worked on. Please have
some patience. Otherwise, please report back again. Thank you
@lele89 Did you try the steps I gave you? You need to go back to earlier levels where these boosters appear for the first time in order to appear again in your game.
