Best Practices for Measuring Onboarding and User Drop-off Points

Hi everyone! 👋 I’m doing some research on best practices for measuring onboarding & identifying user drop-off points. It looks like this channel is mostly answered by bots, but I thought I’d give it a try: 1 - Are you storing onboarding progress on the client or the server? If so, what drove your decision? 2 - If storing on the client, how are you thinking about event flushing and getting the “complete” data?
