when you change it to “is not” and update, then go back to Location Rules, it’s back to “is”
the work-around for this is to delete location rules and start-over.
but if using “category of post,” it must be “hidden in selected pages” and specify “Homepage” or it will show in homepage and other categories. so it’s “hidden in selected pages + Category of Post + is not
but the this doesn’t always work on “mobile only.” if there are more than two category it only works on one of the them.
so for mobile, the sure way to make this work is to “Show in selected page + Single Post + “is” then post id. The problem is that, there can be dozens or hundreds of posts because it shows every published post and draft.
