There are a few reasons that your Hashtags may not appear in your Socials. Most often, this is related to how the Hashtags are set up.
First, if you're not seeing Hashtags in Socials that are not Twitter, this is likely related to your settings in your Socials. In order for Hashtags to be added to a post in these Socials, there must be some text posted. You will need to activate a setting to include some text in the comment that is part of your post.
To activate these settings:
1) Click on your Socials tab
2) Click on the Social in question
3) Click on Edit
4) Activate the toggle for at least one field highlighted below
5) Click Save
The other problem that can happen with Hashtags is that you may have them set up in the Prefix or Suffix section of your Feeds/Socials. We have discontinued allowing Hashtags in these fields, as they were never intended for Hashtags. To edit your Prefixes and Suffixes, please see our tutorial on how to edit these fields.
