They can be (it's a non default but available checkbox on the CN interface) but they have to be very very carefully tested. Normal CentralNotice banners tend to end up being so large on the mobile system that they can be highly intrusive and it is difficult to do things like close the banner.

Do site banners appear on mobile apps and mobile web? I can't recall seeing one. With the growth in mobile, I hope that mobile apps and mobile web will support site banners for important notifications such as Wiki Loves Monuments.

Thanks,

This is an Encyclopedia
One gateway to the wide garden of knowledge, where lies
The deep rock of our past, in which we must delve
The well of our future,
The clear water we must leave untainted for those who come after us,
The fertile earth, in which truth may grow in bright places, tended by many hands,
And the broad fall of sunshine, warming our first steps toward knowing how much we do not know.
Catherine Munro
