Hey there and welcome to Apple Support Communities Upset Komodo,

We can certainly understand your concern and can help provide some insight.

We recommend checking out these steps on how to sync your device and see if that matches up with your procedure.

" Use iTunes to sync your iPhone, iPad, or iPod with your computer

Learn how to sync music, movies, and more using iTunes on your Mac or PC.

If you're using macOS Mojave or earlier or a Windows PC, use iTunes to sync content to your devices. Before you use iTunes to sync content to your iOS or iPadOS device, consider using iCloud, Apple Music, or similar services to keep content from your Mac or PC in the cloud. This way, you can access your music, photos, and more on your devices when you aren't near your computer. Learn more about using Apple Music or iCloud Photos instead of iTunes.

If you use iCloud or other services like Apple Music to keep your content up-to-date across all of your devices, some syncing features through iTunes might be turned off.

What you can sync with iTunes

• Albums, songs, playlists, movies, TV shows, podcasts, and audiobooks.
• Photos and videos.
• Contacts and calendars.

iTunes features might vary by country or region.

Sync or remove content using iTunes

1. Open iTunes and connect your device to your computer with a USB cable.
2. Click the device icon in the upper-left corner of the iTunes window. Learn what to do if you don't see the icon. 

3. From the list under Settings on the left side of the iTunes window, click the type of content that you want to sync or remove.* To turn syncing on for a content type, select the checkbox next to Sync.

4. Select the checkbox next to each item that you want to sync.

5. Click the Apply button in the lower-right corner of the window. If syncing doesn't start automatically, click the Sync button. "

Hi Upset Komodo,

Have you attempted to restart both your computer and iPhone? This will allow both to refresh and reconnect. Here's how to restart your iPhone:

1. Press and hold either volume button and the side button until the power-off slider appears.

2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.

3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo.

This information is from Restart your iPhone - Apple Support.
