I have installed app I can see them on apps store as installed and I can't find them on my apps list so I can not uninstall or open it ' I still receive notification
Have you tried restarting your phone first? (hold down power and volume down together for about 10 seconds until the phone vibrates) Then look and see if the app is listed in the apps list.
It should show up in storage sense. If it does, try moving it to your sd card (if you have one) or move to your phone. You can also delete it from there to try reinstalling.
