Ensure that you have the latest version of the RCA Signal Finder app installed. Go to the App Store, search for the app, and check if there is an available update. If there is, download and install it.

If the issue persists, try uninstalling and then reinstalling the RCA Signal Finder app:
- Long press the app icon until it shakes.
- Tap the 'X' sign to delete it.
