Was the Android version flow-tested by anyone at all at element.io?

When I tried registering a new account, it did not accept my handle. I guessed this because the handle text was red.

But why it didn't like it I can't see because the little box with the error message is outside to the right of the screen (I guess there is a box because I see a little arrow on the right and I understand that this just a web view of something not originally designed for mobile/portrait).

Basically, if this was my ma or any of my non-techie friends, they would close the app now without ever registering.

After I login with my existing account and verify the device via my Linux client it asks me to enter a "recovery key or security phrase".

I enter my security phrase, I get a spinner, the spinner disappears, the 'Continue' button is grayed out. Nothing happens.

These are both flows that (a) a new user would see or (b) an existing user would see, immediately when using the app for the first time.

How is it possible they're broken like this?
