The close reason given also says:
Update the question so it focuses on one problem only.
But I'm struggling to see where there is more than one problem presented?
It also collected some 'Needs details or clarity' and 'Opinion-based' and again, I'm not sure what the argument there is.
It could well be I've missed something, but I'd like to find out the communities opinion.
