Hi! I understand your GoPro Quik app is crashing when you try to download videos on your iPhone with iOS 18.6. Let's work through this together.

First, can you tell me if you've already tried any troubleshooting steps such as updating the app or restarting your phone? Also, are you downloading videos from the cloud or directly from your GoPro camera?

Meanwhile, here are some quick steps to try:

1. Update the GoPro Quik app and iOS: Please ensure both the GoPro Quik app and your iPhone's iOS are updated to their latest versions. Sometimes crashes happen due to outdated software.

2. Force close and reopen the app: On your iPhone, swipe up from the bottom and pause (or double-click Home button if using an older model), then swipe the GoPro Quik app off the screen to close it. Reopen the app and try downloading again.

3. Restart your iPhone: Power off your iPhone fully, wait 10 seconds, then power it back on. This can clear temporary glitches.

4. Check available storage: Make sure your iPhone has enough free storage for the video downloads.

If these don't help, we can try some deeper steps like reinstalling the app or checking your account sync settings.

Does any of that match what you've already tried? Let me know, and we'll go from there!

I tried all these

Thanks for letting me know you've tried those basic steps already. Let's dig a little deeper to resolve the crashing issue when downloading videos on your iPhone.

Since you’re using iOS 18.6, here are some more focused troubleshooting steps:

1. Reset your GoPro Camera Connections on iPhone:
- Go to your iPhone Settings > Wi-Fi and look for any GoPro networks you previously connected to. Tap the ⓘ info button next to them and choose “Forget This Network.”
- Then, also go to Settings > Bluetooth and forget any GoPro devices listed.
- Restart your iPhone and camera, then reconnect via the GoPro Quik app.

2. Disable Private Address for GoPro Wi-Fi:
- Connect your phone to your GoPro's Wi-Fi network.
- Go to Settings > Wi-Fi, tap the ⓘ next to the GoPro network, and toggle Private Address OFF.
- This setting sometimes causes connectivity issues affecting download reliability.

3. Check Account Sync and Permissions:
- Open the GoPro Quik app, go to your profile/account settings, and make sure you are properly signed in.
- Verify the app has permission to access Photos and Files on your iPhone under Settings > GoPro Quik.

4. Try Reinstalling the App:
- Delete the GoPro Quik app from your iPhone.
- Restart your device.
- Reinstall the latest version from the App Store and sign back in.
- Attempt your video download again.

If the app still crashes despite these steps, it might be related to a bug or incompatibility with the current app version or iOS 18.6. In that case, you might want to contact GoPro support directly or report the issue through the app for their developers to investigate further.
