I'd like to be a beta tester for the Android app when it comes out. How do I sign up?
The Android app's 4.0 beta has just been launched to the Beta channel. Opt in at https://play.google.com/apps/testing/..., but first join this community. Version 4.0 has glorious offline sync and a new dark theme.
