Good Afternoon:
I am having a few problems with my phone.
I am unable to connect to my app store.
I am unable to sign in with my apple ID and password
My apps are slow or not working at this time.
Thank you

App Store, iTunes Store, or other Apple services - If you can't connect
Do you have access to another WiFi network where you can try? That has worked for several people.
Try a restart.
Restart your iPhone, iPad, or iPod touch
Try a forced restart.
If necessary
Do a backup and try a factory reset. Then restore from your backup.
Backup - Restore your device from an iCloud or iTunes backup.
