Hi! I understand your Snapshot app on iPhone is not keeping the location setting on "Always" and keeps reverting to "While Using." That can definitely interfere with the app’s functions if it needs constant location access. Just to make sure I understand completely—have you already tried changing the setting in iPhone Settings > Privacy > Location Services, and set Snapshot to "Always," but it still flips back on its own? Also, is your iPhone running any battery saver mode or restrictions?

Meanwhile, here are some common steps that generally help fix this issue:

1. Enable Background App Refresh:
Go to Settings > General > Background App Refresh, and make sure it is enabled for Snapshot. This allows the app to update and access location in the background, which is needed for "Always" permission.

2. Turn off Low Power Mode:
Low Power Mode restricts background app activity and can cause location settings to reset. Check under Settings > Battery that Low Power Mode is off.

3. Check that Location Services are fully enabled:
Go to Settings > Privacy & Security > Location Services, confirm Location Services is toggled on globally, then scroll and select Snapshot, ensuring it is set to "Always."

4. Reinstall Snapshot:
Sometimes corrupted app data causes permission glitches. Try deleting the Snapshot app and reinstalling it fresh from the App Store. Then reconfigure permissions.

5. Restart your iPhone after these changes to ensure the system fully registers them.

If after these you still find the location settings flipping back, it might be due to system-level restrictions or a bug affecting the app’s permission retention. In that case, checking for any iOS updates (Settings > General > Software Update) and updating Snapshot to the latest version is advisable.

Would you like me to guide you step-by-step through any of these, or do you notice anything unusual with your current settings that we can address first?
