Hello, The levels after 2390 are currently only available on Facebook, they are yet to be released on mobile. For information about boosters, please read here: https://care.king.com/en/candy-crush-saga/boosters-messages-842482091 Kind regards, Johnny This does not help with all my lost boosters.
My friend plays on her phone as has access to high levels than I do. Additionally, I shouldn't lose my boosters because I was able to pass levels without using them. I do know how many boosters I had before I lost them.
