Re: Can't get a reward for watching ads

Sometimes ads are buggy and the problem will most likely solve itself. However, you could try to reset your advertising ID:

Android:
Exit/Close the game first
Open Settings on your mobile
Search for Google settings (skip the second step if you have Google settings as icon in your widget area)
Open Google settings and then search for Ads
Open that and check for option to reset advertising ID
Click ok
Exit settings
Close the game from recently opened apps

iOS:
Settings --> Privacy --> Advertising --> Reset Advertising Identifier
