A. 1. Check Internet Connection: Ensure you have a stable internet connection. Try switching between Wi-Fi and cellular data to see if the issue persists. 2. Wait and Retry: Internal server errors can be temporary. Wait a few minutes and try accessing the app again.

B. 3. Clear App Data: Go to Settings > General > iPhone Storage, find RAISE365, and tap on it. If there’s an option to 'Offload App', do that to clear data without losing your information. Then reinstall the app.
