Our sites use a customized version of the Shout Outs PowerApp but it won't load on an iOS device via the SharePoint App or via Safari or Chrome browsers. Works fine on Android devices and any desktop/laptop device (Macbook and Windows, all browsers). Gives an error saying unable to connect due to cookies needing to be enabled in the browser. Cookies are enabled, so that can't be the problem. This seems to be a known issue. When will MS get this working for iOS?
