Hi! I understand your RISE app is crashing and losing your sleep data, also showing messages about missing data. That can definitely interfere with tracking your sleep accurately.

To help me guide you better:
- When does the app usually crash? (e.g., on startup, when syncing data, or at a specific action)
- Are you using any other sleep tracking apps like Sleep Cycle connected with RISE?
- Have you recently updated the RISE app or iOS 18.6.2 on your iPhone?

In the meantime, here are some steps that can often resolve crashing and data syncing issues on iOS devices:

1. Restart your iPhone: Sometimes a simple restart can refresh system resources and fix temporary glitches.
2. Ensure RISE App permissions:
- Go to Settings > Privacy > Health > Sleep and make sure RISE has permission to read and write sleep data.
- Also, check if RISE has permission under Settings > Privacy > Motion & Fitness if applicable.

3. Force close and reopen RISE:
- Swipe up from the bottom (or double click the Home button) to open the app switcher, swipe the RISE app away to close it, then reopen.
4. Update the RISE app: Check the App Store for any updates, as newer versions often fix bugs related to crashes and syncing.
5. Check Apple Health data sync:
- Open Apple Health, ensure your sleep data for the nights you are tracking appears there correctly.
- If you use another app like Sleep Cycle, open that app to push its latest data to Apple Health, then reopen RISE to sync.
6. Reinstall RISE app: If the above doesn't help, backup your data if possible, delete the app, and reinstall it. This can clear any corrupted files causing crashes.

If you've done some of these steps already or the problem persists, please let me know. I can then help you investigate deeper, such as checking app logs, verifying any server side issues, or adjusting advanced settings.

Are you okay to try these and tell me what happens?

Restarting my phone does resolve it but I have to keep doing that

Thank you for letting me know that restarting your iPhone temporarily resolves the RISE app crashing issue but you have to keep doing it. That tells me the problem might be related to memory or app stability on your iOS 18.6.2 device.

Since restarting fixes it only for a while, let's try some deeper steps tailored for your iPhone:

1. Clear app cache and data (via offloading):
- Go to Settings > General > iPhone Storage.
- Find the RISE app, tap on it.
- Tap "Offload App" (this removes app but keeps documents and data).
- Then tap "Reinstall App."
This can clear any corrupted temporary files without losing your data.

2. Check available iPhone storage:
- Still in iPhone Storage, ensure your device has enough free space (ideally more than 1-2 GB). Low storage can cause apps to crash or behave oddly.

3. Close other background apps:
- Swipe up and hold (if no home button) or double-click home button (if present) to bring up app switcher.
- Swipe away other apps running, especially apps that track health or fitness data, to reduce memory pressure.

4. Update iOS and RISE app:
- Go to Settings > General > Software Update and check if any update beyond 18.6.2 is available. Sometimes system updates improve app stability.
- Open App Store, check if RISE app has any updates pending.

5. Reset network settings: Sometimes faulty network connections create syncing issues causing apps to crash.
- Settings > General > Reset > Reset Network Settings (Note: this resets Wi-Fi passwords and VPNs, so you’ll need to re-enter those).

6. Check for conflicts with other health apps:
- If you have other apps writing sleep data to Apple Health (e.g., Sleep Cycle), temporarily disable write permissions for RISE in Settings > Privacy > Health > Sleep to test if conflict causes instability.

If these steps don’t improve things, the issue might be an internal app bug specifically on iOS 18.6.2. In that case, reporting the crash logs to RISE support at [email protected] could help developers fix the problem. Meanwhile, I can assist you with gathering logs if needed.

Would you like me to guide you through any of these steps or check for iOS updates first?
