A. Try refreshing the app or restarting your device to see if this resolves any temporary glitches. If the location search is still not functioning properly, check your device's location settings to ensure that location services are enabled for the Waterstones app. Go to Settings > Privacy > Location Services and make sure Waterstones is set to 'While Using the App' or 'Always'.
B. If the location search continues to be problematic, consider manually entering your location or using the nearest major city as a reference. This may help you find the nearest store more effectively.
