[iOS][Glitch] Pic Collage is stuck at installing (I can't install the app)
1. Reboot your iPhone normally.
2. If the apps are still stuck on the home screen, try logging out of the App Store temporarily. Navigate to Settings -> Store -> Apple ID -> Sign Out. Now open the App Store and Navigate to the Featured section. Scroll to the bottom of the page and touch the Sign In -> Use Existing Apple ID. Log in and the stuck apps should reset.
