Hi there! I can help you with the issue you're having with the Doctolib app on your iPad. It sounds like it's working perfectly on one iPad but not the other. Let's start by figuring out a few things.

1. iPad Model and iOS Version: Can you tell me which model of iPad you’re using? Also, it would be helpful to know if the iPad that isn’t working is updated to the latest iOS version.

2. App Version: Have you checked if both iPads have the same version of the Doctolib app installed?

3. Network Connection: Is the iPad that can't open Doctolib connected to the internet? Sometimes, network issues can prevent apps from functioning.

4. Error Messages: Are you seeing any specific error messages when you try to open the app? That information can really help narrow down the problem.

Once I have a bit more information, I can guide you through some steps to resolve this. Thank you!

The one that does not work is an old iPad on 12.5.7 which is the latest émersion for this machine I have reloaded the app which said it was the latest version for this machine

Thank you for the information! Since your iPad is running on iOS 12.5.7, which is the latest version for that model, it’s possible that some apps, including Doctolib, may not fully support older versions of the operating system or may have features that require a newer version.

Here's what you can do:

1. Check Compatibility: Sometimes, apps, including Doctolib, may have features or functionality that isn’t compatible with older iOS versions. If you are having issues after reloading the app, it may mean that the latest version of Doctolib is not optimized for iOS 12.5.7.

2. Use Safari or Another Browser: If the app isn't working, you might try accessing Doctolib through Safari or another web browser on your iPad. Sometimes, web-based access can provide an alternative if the app is having issues.

3. Clear Cache: If you're trying to use Safari, clearing the cache or cookies could help resolve any loading issues:
- Go to Settings > Safari > Clear History and Website Data.

4. Reinstall the App: Since you've already reloaded the app, you may want to try deleting it completely and then reinstalling it again from the App Store, ensuring that your device can still find it in the App Store since newer apps sometimes get phased out on older iOS versions.

If none of these steps work, the last measure would be reaching out to Doctolib’s support team directly at [email protected] for further assistance, as they may have additional insights regarding compatibility with older devices.

Are you satisfied with the solutions I provided, or is there anything else you’d like me to help with?
