If you are having issues with updating World War Doh on your android device, you may need to clear the cache for the Google Play Store and Google Play Services.

Please use the following steps:
1) Go to your Settings Menu
2) Go to Apps or Application Manager
3) Tap on Google Play Store or Google Play Services
4) Tap on Storage
5) Tap on Clear Cache
6) Tap on Clear Data
7) Tap OK

Please follow these steps for both Google Play Store and Google Play Services. Once you've cleared both apps' caches, wait for about 2-3 minutes and start up your Google Store. Once everything comes back, you should be able to update the game!
