Lost rewards

Hi @vimala and welcome to our adorable Community 😊 Can you give me more details about what happened? Are you referring to boosters or rewards from challenges? The more you tell me the more I will be able to help you. Thank you for your understanding.

Hi again @vimala The boosters are not meant to be saved on our devices because sometimes it might happen that we lose them when the app crashes or updates, hence it's better if we just use them while playing. You can read more about safeguarding your boosters on the link below. Have a wonderful day and keep crushing 🤗
