Fox laid off much of their marketing department and then hired essentially temporary staffers. This isn't necessarily unusual. Studios will bring in people to run specific types of campaigns and there is considerable turnover. But this was essentially chaos at Fox with no one really running the campaign. Even before that, a lot of Fox's marketing department was leaving before they could be laid off.
Deadline has some details about what was going on:

I can't get into more details, but I can confirm that is 100% correct and still going on at Fox.
