Hi dianafromtalent,
Thank you for posting in Apple Support Communities! Sounds like there may be a connection issue happening. Have you tried connecting your iPhone to a different network? If you're using cellular, you can try a Wi-Fi network.
You can also try restarting your iPhone by pressing and holding either volume button and the side button until the power off slider appears. Drag the slider to power off and wait about 30 seconds. Press and hold the side button until you see the Apple logo to power it back on.
Restart your iPhone
Once back on, you can check to see if this continues.
Also, be sure there are no software updates that need to be installed by going to Settings > General > Software Updates.
Update your iPhone, iPad, or iPod touch
Be sure to back up your data before installing any updates. If you use iCloud to back up, you can go to Settings > Your Name > iCloud > iCloud Backup > Back Up Now to initiate one.
How to back up your iPhone, iPad, and iPod touch
Hope that helps!
