So, how can we make it clear and engaging?
Because of the new product offering and technical constraints, we decided to explore different ways to explain how the product works in a very clear way, while still keeping the experience engaging. After more user tests, we decided to move forward with the 4th solution here, which is more illustrative and explains how the interests get auto-invested in a very clear way. Surprisingly, participants in the user tests said that they really appreciate this feature, otherwise they're going to spend the extra earnings.
