@grant. I’ve noticed that any name added to Basic Plus (that has ‘visable in the marketplace’) next to it in our back office, is not visable in the marketplace) when I search for the names.
There seems to be a cut off point but I don’t know the exact date. Names added before the first week in October are in. Names added in the last few weeks are not in.
Edited to add: I’ve just blue buttoned this, as it’s probably something for your tech guys rather than you.
