What am I beta testing in OneCloud for Android?

[Spocktacular]

In the Google Play store, I signed up for the OneCloud Beta program, and downloaded the latest beta release. Now I have no idea what to "do" with it. What exactly am I testing? What areas/features should be targeted to help Microsoft Engineers? I can't find any release notes.

PS: I am hoping "use it as normal until something functions awry" (based on supposition?) isn't the answer. That's not to be snarky. I fully understand functional testing so I really want to help.

Thank you.

My guess is that you are talking about Onedrive :)

By joining a beta program you are receiving earlier builds with newer functions and features but also bugs etc! Use it as normal and report any bugs etc
