Why is the View_Signatures_vod button not showing up offline for Events Management?
This is working as designed. The View_Signatures_vod button is not designed to be viewed offline with Events Management. The View_Signatures_vod button is only available online in order to audit signatures.
Alternatively, the Digital Sign-in Sheet may be used to view who has signed in to the Event offline, however, it will not display the signatures.
