Hello! I understand you're having an issue with the Bonjour RATP application on your iPad not showing the bus maps. To help you best, could you tell me a little more? For example, are the bus maps not loading at all, or do you see some sort of error message? Also, does this happen only with bus maps or with other maps and routes in the app as well?

Meanwhile, here are some initial steps we can try to resolve the problem:

1. Check Internet Connection: Make sure your iPad is connected to a stable internet connection (Wi-Fi or mobile data). Maps need internet to load properly.

2. Update the App: Verify that the Bonjour RATP app is updated to the latest version via the App Store. Older versions might have bugs affecting map display.

3. Restart the App: Close the app completely (swipe up from the bottom and pause, then swipe the app off the screen) and reopen it.

4. Clear Cache or Data: Although iOS apps don’t have a straightforward cache clear button, uninstalling and reinstalling the app can help if some data is corrupted.

5. Check Location Permissions: Ensure that Bonjour RATP has permissions to access your location. Go to Settings > Privacy > Location Services, then check for Bonjour RATP and set it to “While Using the App” or “Always.”

6. Try Viewing Other Transport Modes: To narrow down the issue, see if metro or RER maps are working in the app. If only bus maps fail, it might be a specific bug or missing data in the app.

Could you please let me know if you've tried any of these steps already, or if the issue is happening under specific conditions? That will help me provide more precise guidance.

Are you satisfied with this initial approach so far?
