There is a blank Related List in Event on CRM iPad, however, Event Online is normal.
A user adds an Approval History related list on the page layout of an Event. Currently, the Approved History related list is not supported through the Page Layout Engine. The Event Online hides the Approval History related list entirely (no blank space).
The user can consider removing the Approval History related list from the page layout as a workaround.
