On any SharePoint site (modern or classic) on iPhone Safari, going from portrait to landscape back to portrait results in a gap at the bottom of the page. You have to pinch/zoom out to get the page to snap back into place at the correct size.
Screenshots attached from https://www.makinghomeaffordable.gov, but it also happens on O365 modern sites as well.
