Re: There's a bug here: when unselecting the option, the FAB will not come back. Nor dav drawer. S7 edge, Android 6.0.1, French version
When unselecting which option? The "two panel mode variety" or the "two panel mode"?
As long as you keep the "two panel master switch" enabled, there is no FAB.
And then if "two panel master switch" is off, you can turn the FAB on and off, except - on 5.0+ with Material theme where the setting is grayed out, but the FAB is always there.
