Hey there jrm1264,
Thanks for reaching out to the Apple Support Communities. To get started, we do want to let you know that the cloud icon you're seeing when redownloading the app would just mean that you have previously downloaded this app before, and would not mean that the app is stored in iCloud.
If having issues with the Ring app not working as expected, be sure to go through any additional step you may not have already tried from the following resource: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support
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.
If still running into issues after going through the steps above, we'd recommend reaching out to the app developers for additional help. Check out this next link for steps on how to reach out to the app developers: How to contact an app developer - Apple Support
We hope that's able to help.
Take care.
