my app store on my 6plus is not working...contents are not loading..please help

Turn your device off and back on. If this doesn't help, sign out from your account and sign back in.

Also, you can try resetting your settings.

• Press and hold the Sleep/Wake button
• Press and hold on the Home button
• Keep holding both buttons until the display turns off and back on with Apple logo on it.

Alternatively, you may go to Settings - General - Reset - Reset All Settings
