I have a Facebook Insights Query with the date range of thisyear. The first time, the query ran fine. I added a few metrics and now the query will only pull data for April and not since the start of the year. Query ID is cqepr8QdQqe8NpI2Rc7lIrYu0Wo3J0.
Unfortunately there is an issue with the Facebook API at the moment, limiting the amount of posts returned in the query results. See https://developers.facebook.com/bugs/2297783020445879/ for more details. We'll let you know as soon as there's more information from Facebook in this matter.
