How do I get ads back for extra lives?

Welcome to Soda Community @lorilgl

I am sorry to read that the ads have stopped appearing in your game 😕

These ads is a feature which is still in testing. All the features that are in testing are moved around to be tested by as many players as possible. In that process, some players will have those special features for weeks, some have it for months some players have it for years, and some have never seen any ads (like me)

We do not know which group you fall into. And, until the feature is done testing, it won't become a permanent feature!

I suspect you have been moved to another group, which (temporarily) has no ads. Ads might return in your game; all you can do is make sure your game and device has the latest updates.
