Changes for iPad
iOS 13.5 includes the Exposure Notification API to support COVID-19 track and trace apps from public health authorities.
I'm intrigued as to how they have adapted Face ID to work accurately with a face mask.
From experience, some may have issues with certain apps. When opening an app eg Facebook, Whatsapp etc you may get the message "this app is no longer shared with you, please purchase from the AppStore". It is a bug in the system, Apple are aware and looking to fix. I googled and found if you go to Settings, General, iPhone storage, choose appropriate app eg Facebook, click offload app then wait. It does not delete your stored settings etc. Then click the cloud icon to re-download the app. Worked for me.
