Thanks for following up! Here's some of things that tripped me up:
1. The lack of in depth docs.
2. The set up and usage of metrics was focusing. This was the main use case I was hoping Metabase could help me with, and it felt like an addon feature.
3. For whatever reason, managing dashboards was really confusing, and the UI [1] didn't seem to match the docs.
[1] I was using the mac version.
