A. If you encounter an error when selecting a number, try restarting the app. Close it completely and reopen it to see if the issue persists. If it does, clear the app's cache by going to your device's settings, finding the textPlus app, and selecting 'Clear Cache.' This can help resolve temporary glitches.

B. Ensure that your app is updated to the latest version. Go to your device's app store, check for updates for textPlus, and install any available updates. Developers often release updates to fix bugs and improve performance.
