If you need to move on to something else in the middle of creating a post, you can save it as a draft and return to it later. If your company is still in the “TO” field, other users on the job will also be able to access and edit your draft, as well as post it.
On mobile simply hit X during the create process and you’ll be given the option to save a draft. On web there is a Save Draft button.
When you’re ready to get back to it you can tap your quick filter drop-down (default set to "Everything") and then tap "Drafts."
On the web click “Everything” to list the preloaded quick filters of your feed - including Drafts
