Does work with latest SuperWall 3.x SDK

**Describe the solution you'd like or the information you're missing**

Would like for revenue tracking via SuperWall 3.x SDK to work.

**Additional context**

Events are being sent from my app to TD using the sample SuperwallService code provided. However the revenue is not being tracked.
