First I deleted the app from my iPad. Used Safari to search for "ezviz app download" and selected the "Mobile app - ezviz". Next select your device type. For me, I selected for iPhone as it does not mention for iPad. Next you are sent to the App store with Get/Buy/iCloud for this EZVIZ International app. This new download works for me as they probably fixed the bug.
