Hi there! I see you're having trouble with the Ouranos app showing an "unable to load data" message on your Samsung Galaxy A71. Let's get this sorted out together.

First, to better assist you, could you tell me a bit more? For example:
- Is this happening right when you open the app, or only when trying to load certain features?
- Are you connected to Wi-Fi or cellular data?
- Has the app worked properly before, or is this a recent problem?
- Have you tried any steps so far, like restarting your phone or reinstalling the app?

In the meantime, here are some initial steps you can try on your Galaxy A71 to resolve loading data issues:

1. Check Internet Connection: Sometimes a weak or unstable network can cause data loading to fail. Try switching between Wi-Fi and mobile data to see if it improves.

2. Force Close and Restart the App:
- Tap the Recent Apps button.
- Swipe the Ouranos app off the screen to close it.
- Reopen the app and check if data loads.

3. Clear App Cache and Data:
- Go to Settings > Apps > Ouranos.
- Tap on "Storage."
- Tap "Clear Cache," then "Clear Data."
- Restart the app and log in again.

4. Update the App:
- Open the Google Play Store.
- Search for Ouranos and check if an update is available.
- Install any updates and try again.

5. Restart Your Phone: Sometimes a simple reboot can fix temporary glitches.

If the issue persists after these steps, it might be related to a server-side problem or app version compatibility. Let me know what you've tried and I'll help you from there!

Are you able to share any other details about the problem?
