Why did I get zero credit on rocket race?

Hello @saulocabral2020

I am sorry you experienced this and I can well imagine your disappointment. I too have experienced this and it has been reported.
Do you perhaps play on multiple devices? In my case the candies were counted on 1 device and not on another.

Unfortunately I don't have a solution, all I can advise you is to follow the next steps:

Restart: Force close all open apps and restart your device. Leave it switched off for at least 10 seconds, then turn it on again.

Updates: Make sure you have the latest game and device updates

Memory: Do you have sufficient memory on your device? King recommends having at least 2GB free memory storage to run the game smoothly. 

Connection: Try to connect to a WiFi connection instead of using cellular data

Clear Cache: in Android: go to settings - tap on apps - tap on candy crush soda - tap on storage - tap on clear cache (not data❗️)

————— in iOS: go to settings - tap on Safari - tap on Clear history and website data
