Underlock App Not Downloading from iCloud
My phone broke and I got a new one, when I downloaded the iCloud backup from the previous phone onto my new one, the new one still had the Underlock App on it but had the iCloud symbol next to it. When I tried to tap on it on the phone to redownload it from the cloud, it said the app had been removed from the app store and gave me two options: "keep" or "remove". I kept it and because of the backup file, I know the data (photos and videos) are still on my phone but because I can't open the app I can't access them. I know they're there and I need them but I can't get to them. I've tried data extractor programs on my computer and haven't figured it out yet. Does anyone know how I can retrieve the data on the app?
