Comments on some Facebook posts are not being imported right now and since today 12pm PST. This is due to a Facebook permission which was revoked from us today.
Posts for which comments are not being imported include: - some videos, - posts where the page shares a Facebook group it might also include some other kind of posts, but regular posts are not affected. We're in the process of re-enabling this permission, we will keep you updated as soon as possible.
