@JBassett you are right, firebase retry screen has the same issue. Let me remove from there.

@JBassett do you happen to know what screen this is found on? https://github.com/home-assistant/android/blob/master/app/src/main/res/layout/fragment_manual_setup.xml#L32

I was expecting to see a button label :)

Edit: its actually pictured in my previous comment which seems to be ok, so this must be the only instance its allowed? Its the ok button on the manual setup screen lol

That is the manual URL entry for connecting to a Home Assistant instance that you covered with the second set of screenshots.
