Hello, since yesterday i have encountered a new problem with my iPhone. When I try to install any 3rd party app it doesn't install. I click install and then a new icon on my homescreen appears but when it installs it is blank. For example I tried to install AppValley I got that blank icon. Here you can see it: https://imgur.com/a/yl9eCTZ The app doesn't show up in profiles. I tried to install TweakBox it worked because it is verified by Apple. Please someone help me! I have already tried to reset my phone and tried to upgare to the newest version. I have iOS 11.4.1 blobs but I can't downgrade because my Apple Watch is on WatchOS 5 so it won't connect to iOS 11.
