EDIT: We have now started rolling out a build that should resolve this issue. If you are experiencing this issue please update your game to version 25.1.2 build 1211

Some Android players who have updated to version 25.1.2 are experiencing an issue with Mystic Vision. They are able to watch the ads, but are not receiving the rewards. 

We are currently investigating this and hope to resolve the issue as soon as possible. Our apologies for the inconvenience!
