Hi there! I understand your Sheytoon app opens but doesn't show any photos. Let's see if we can get this sorted out together.

To start, can you tell me if this happens all the time or just with certain photos or profiles? Also, have you checked if the app has permission to access your photos or internet? Sometimes access restrictions can cause photos not to load.

In general, here are some steps you can try on your iPhone with iOS 15.8.5:

1. Check App Permissions:
- Go to Settings > Privacy > Photos.
- Find Sheytoon in the list and make sure it has permission to access your photos.

2. Check Internet Connection:
- Ensure you have a stable internet connection via Wi-Fi or cellular.
- Try switching between Wi-Fi and cellular to see if photos load in either.

3. Force Close and Restart App:
- Swipe up from the bottom of the screen and pause to open the app switcher.
- Swipe the Sheytoon app off the screen to close it.
- Open the app again.

4. Update the App:
- Visit the App Store and check if there's an update available for Sheytoon. Installing the latest version can fix many bugs.

5. Restart Your iPhone:
- Hold the power button and slide to power off.
- Turn your phone back on and open the app again.

6. Reinstall the App:
- If the above steps don’t work, try deleting Sheytoon and reinstalling it from the App Store.

If none of these resolve the issue, it might be related to a server problem or a bug that the Sheytoon team needs to address.

Would you like me to help you check your app permissions together now? Or have you already tried some of these steps? Let me know!
