Hello JowC,

We don't suggest reverting to a previous iOS version, as each update contains security patches and information to keep the content and data on your iPhone safe, and ultimately improve performance. With that said, installing an outdated version of iOS on your iPhone isn’t supported.

If your iPhone is freezing while using specific apps, try these steps to see if they resolve the issue for you:

1. Close and reopen the app

Force the app to close. Then open the app to see if it works as expected.

2. Restart your device

Restart your iPhone or restart your iPad. Then open the app to see if it works as expected.

3. Check for updates

To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available. If updates aren't available for the app, update the software on your iPhone or iPad.

4. Delete the app, then redownload it

Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed.
