Perhaps to visit your iCloud account through the login
on a web page; or use another device to login to check.
•Sign in and use iCloud.com - Apple Support
•Sign in with your Apple ID - Apple Support
•Web-only access to iCloud - Apple Support
•If you can't connect or sign in to iCloud - Apple Support
Also you may try and see, if through shut-down and restart
the antics of your iPhone may self-resolve; it could happen.
Or plan on setting an appointment with authorized service?
