I can't write a post

What you see: the share box at the top of the feed is missing, or Post stays grey.

Why - The share box is missing: your role does not include Create posts. See What you can do in the News feed. Ask your workspace admin. - Post stays grey: there is nothing to post yet. Write some text, or add a photo, video, poll, event or link. A poll also needs a question and two options before Done turns blue. - A post type's button is greyed out: a post carries one kind of content at a time. If you attached a photo, Poll, Event, YouTube and Link are off. Remove the attachment with its × to use another.
