Hello,
Recently, I was trying to set up the RSS feed for a SharePoint form library. Everything worked fine except one people and groups field. The RSS feed does not show this field even it is active in RSS settings and when it's not blank. I have also tested a solution creating a new people and group column but the same issue appears. Moreover, in the RSS feed is working for other people and groups fields.
Could you please help me with this problem? Is it possible that there is a limit for such fields in the list?
