Busy Alpha 2 play testers best use of time?

I'll be an Alpha 2 play tester, but I have limited free time due to work, relationships, and socializing compared to others. What would be the best use of my time when play testing Alpha 2? I would love for developer feedback. I'm super excited to be a part of this project, I participated in the Alpha 1 play test, have been following this project for 4 years now, and watch every monthly update livestream. I just want to feel like I'm contributing something with the time I have towards Alpha 2's play testing, and would like a little direction in placing my efforts. Thank you in advance.
