Candy crush saga won't download

Hi @Christy39
We warmly welcome you to the Friendly King Community's Candy Crush Saga forum.😊

Such problems can be seen in the Google Play Store. First, make sure you have a strong internet connection. It’s best if you can connect to a Wi-Fi network. If you don’t have access to Wi-Fi, make sure you have a strong mobile data connection. Then try your download again. 
If you still get the same problem after doing this, check the troubleshooting below.

This gives the app a fresh start and can help fix issues. 

1. Open your device's Settings app .
2. Tap Apps & notifications  See all apps.
3. Scroll down and tap Google Play Store .
4. Tap Storage  Clear Cache.
5. Next, tap Clear data.
6. Re-open the Play Store & try your download again.

Let me know.
