Hi there! I see that your AllTrails app on your iPhone briefly shows the front page and then fades to black. Let's get to the bottom of this together.

To start off, could you tell me if this happens every time you open the app or just intermittently? Also, have you tried any steps already to fix this, like restarting the phone or the app? Knowing this will help me tailor the fix better.

Meanwhile, here’s a simple step-by-step guide to try and resolve this issue:

1. Check Your Internet Connection
Make sure your Wi-Fi or cellular data connection is stable. Sometimes the app fails to load properly if the connection is unstable or slow.

2. Force Close and Reopen the App
Swipe up from the bottom of your screen (or double-click the Home button) to see your app switcher. Find AllTrails and swipe it up to close completely. Then reopen it.

3. Enable Background App Refresh for AllTrails
- Go to Settings > General > Background App Refresh
- Make sure Background App Refresh is turned on, and toggle it on specifically for AllTrails if you see it listed.

4. Sign Out and Sign Back In
Open the app, sign out of your AllTrails account (if accessible), then sign back in. This can resync your account and fix some loading issues.

5. Reinstall the App
If the issue persists, try deleting the AllTrails app and reinstalling it from the App Store. Don’t worry; your saved hikes and data should remain safe if you’re logged into your account.

If you've already tried some of these, just let me know which ones, and we can dive deeper from there. Also, if you have any error messages or other symptoms, please share those.

Does this help you get started? Are you comfortable trying these steps now?

When I turn on ap, the screen shows the front page briefly and then fades to black.

Thanks for sharing the details again—that helps me focus on the issue with the AllTrails app fading to black right after showing the front page on your iPhone running iOS 18.7.

Based on this, here are some tailored steps that could help resolve it:

1. Update Your iOS Version
Even though you’re on iOS 18.7, it’s always good to double-check if there's a newer minor update or patch. Go to Settings > General > Software Update and see if anything is available. Sometimes app performance issues get fixed in iOS updates3.

2. Update the AllTrails App
Make sure you have the latest version of AllTrails from the App Store. Developers often release fixes for bugs like blank or black screens.

3. Clear App Cache/Data by Reinstalling
Since the black screen happens right after startup, it might be corrupted temporary data.
- Delete the AllTrails app from your iPhone.
- Restart your device.
- Reinstall the app from the App Store.

4. Check Auto-Lock Screen Settings
Sometimes, iPhone’s auto-lock settings turn the screen black automatically. While it usually locks after a time, it’s worth confirming it's not interfering here:
- Go to Settings > Display & Brightness > Auto-Lock
- Set it to a longer time or Never temporarily to test if the screen fades to black because of this1.

5. Ensure Background App Refresh is Enabled
This ensures AllTrails can load content properly:
- Settings > General > Background App Refresh and make sure it’s on for AllTrails.

6. Sign Out and Back In
If you can get the front page briefly: try signing out of your AllTrails account, then log back in to refresh your session.

If after these steps the problem persists, there may be an issue specific to your device’s settings or a rare bug. At that point, I’d recommend contacting support directly at [email protected] so they can investigate further on their backend.

Would you like me to help guide you through any of these specific steps now? Also, have you noticed if this black screen happens after a specific action, like searching or loading a trail, or is it right as the app starts?
