Hello @Beatty1921 and welcome to our wonderful community. I have seen this same statement from another player and I am not sure if it is a glitch or not but I will elevate it to the Community Managers. First I need to check something - are you still able to collect the sugar drops and you see the number collected increase - but at the various milestone you don't receive any rewards? Are you connected to the internet? Sometimes if you don't have a strong and steady signal with the internet you won't get any rewards until you reconnect.
Anyway - please let me know and in the meantime I will elevate this problem. Thank you.
