Hi! I understand you're having trouble opening the Luminar app on your iPad Pro. Let's get this sorted out together.

To start, can you confirm whether the app was previously working on your iPad or if this is the first time you're trying to open it since installation? Also, did you update to the latest version of Luminar Mobile for iPad? Sometimes an update can resolve opening issues.

Meanwhile, here is a step-by-step approach to try:

1. Force close the app: Double-press the Home button (or swipe up from the bottom and pause on newer iPads without a Home button) to bring up the app switcher. Swipe up on Luminar to close it fully and then try reopening.

2. Restart your iPad: Press and hold the top button and either volume button until you see the slider; slide to power off. After it's off, press and hold the top button again until the Apple logo appears.

3. Check for updates: Open the App Store, tap your profile picture, then scroll to see pending updates. If Luminar Mobile is listed, update it.

4. Reinstall the app: If the above doesn't help, try deleting the Luminar app by pressing and holding its icon until it jiggles, then tap the 'X'. Re-download it from the App Store.

5. Check available storage: Low storage can interrupt app launches. Go to Settings > General > iPad Storage to confirm.

If you have tried these or can tell me more about the problem (any error messages, when it fails to open), that would help me tailor the next steps.

Are you currently on the latest iPadOS version? Compatibility can sometimes be an issue if the OS is outdated.

Let me know what you have tried so far, and I’ll guide you from there!
