Hi everyone,
We have noticed an issue regarding the Zetadocs content type for a few of our customers. Columns for this content type and its associated view have been hidden.
These columns were Created, ZetadocsRecordLink and ZetadocsRecordLinkType.
I managed to find the pages for these columns in SharePoint by looking at another column's URL and making an educated guess on what the URL would be for that column. I then selected the option in SharePoint to set the column from Hidden to Optional.
Even after this, I still couldn't add the column back at the site level via the content type, or view level, it's just not available from the list of columns.
Has anyone else had this issue, so far three of our SharePoint online customers have this issue.
